Losing steam

On 4 September I launched a software project to create an asset loader for JMonkeyEngine based on the Open Asset Importer, aka Assimp.

I've now published 2 test versions of MonkeyWrench, my LWJGL-based library. Version 0.5.1 works okay, mostly, and in many cases it is clearly superior to the standard jme3-plugins loaders. However, I have doubts whether anyone will use MonkeyWrench, and my enthusiasm for the project is waning.

After 53 days of often-intense coding effort, I have a nice little open-source project: about 5300 lines of Java code at GitHub (not counting blanks and comments). I also learned a lot, of course. But I think my main accomplishment has been to document 17 issues in JMonkeyEngine, many of which have since been solved. (My project coincided with Hacktoberfest, which is perhaps why JME had more coding activity than usual.)

I also documented 5 issues in Assimp, though I'm not optimistic they'll ever be solved. That project has a huge backlog of open issues (currently 683) and doesn't seem very active.

My original plan called for investigating the Kotlin version of Assimp, but I see now that would be a separate project. Furthermore, the Kotlin project is even less active than Assimp itself: no commits since 2020. I'd probably wind up maintaining my own fork, which would defeat the purpose. Plus I've very little interest in learning Kotlin.

It's time to start winding down the project, making sure my code is clean and my documentation is adequate, and pursuing each residual issue to the best of my ability.

yknow what fuck it

one of these days soon imma start a blog focusing on shitty old opengl renders

"webcore" this, "early internet" that, "y2k" whatever whatever

the absolute power that some hacked together 3rd project by a dev still figuring out lwjgl 2 or like glfw or glut or smth has more power than that tbh

like you cant tell me that innapropriately detailed textures without any lighting for a game that is probably just a proof of concept that a dev can like use c++ or java 1.4 is immaculate vibes

#opengl #gl #y2k #lwjgl #c++ #graphics programming #aesthetics #fuck you

[plazmindev]

so this week i've been working on lightmaps, and I thought that they would be easy to implement since I just had to take the bytes from the BSP and use them in a texture but ohohoho no it was not

so the first thing that went wrong was me parsing the lightmap UVs the wrong way, thankfully a really good programmer who's experienced with BSP files helped me out with that. i also removed all lighting from the scene shader leaving only the fog

but i was having an awful time figuring out why lightmaps weren't loading, they only loaded if i binded the texture AFTER creating it instead of before, but that would only cause the last texture to be loaded to show up and also messed up Dear ImGui

near the end of this week i was so sure that I had almost finished loading the lightmaps, but no matter what I did it didn't seem to change anything about the texture

but then i accurately converted the lightmap uvs and it turns out I was accidentally using the Dear ImGui font atlas as a texture

i still have no idea why this happened

but multiple hours of staring at my screen later I finally finished it and i was SO HAPPY

that's basically all i did this week, probably gonna turn these weekly devlogs into a regular thing unless i forget about it like every other thing i say i'm gonna do

Contains bindings to the OpenGL ES, a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded systems - including consoles, phones, appliances and vehicles. So lets get started with the Shader class. But before we do that, we should load the shaders and compile them, that is what we are going to look for now. In this tutorial, we are going to draw our first triangle onto the screen. In the previous tutorial, we have got some theory on the GLSL language, and we learnt some of the syntax.

Making a 2D game with LWJGL 3 and Java - YouTub

Twitter this video we take a look at how to create Flappy Bird from scratch in Java, using LWJGL 3 for OpenGL.

For porting existing LWJGL 2 code to LWJGL 3, see the migration guide For more code examples, see the LWJGL samples and the lwjgl3-demos repository (nightly build required).

LWJGL comes with rich documentation, you can browse the javadoc online starting here.For more information, FAQ, guides and tutorials visit the wiki.The Memory FAQ, Bindings FAQ and Troubleshooting pages are especially useful.

This comes at a cost: You now need to carefully specify the dependencies one by one. Now the base code is much more modular, and we can be more selective in the packages that we want to use instead of using a giant monolithic jar file.

LWJGL 3.1 introduced some changes in the way that the project is built.

For older hardware there will possibly be an OpenGL 2.1 version available In the course of the tutorial we will use OpenGL 3.2 Core Profile for creating a small game with shaders.

Stbimage image example java lwjgl

It is thus our job to tell OpenGL how it should sample its textures. Texture sampling has a loose interpretation and can be done in many different ways. The resulting texture coordinates would then look like this: We only have to pass 3 texture coordinates to the vertex shader, which then passes those to the fragment shader that neatly interpolates all the texture coordinates for each fragment. The top of the triangle should correspond with the top-center of the texture image so we take (0.5,1.0) as its texture coordinate. The same applies to the bottom-right side with a (1,0) texture coordinate. We want the bottom-left side of the triangle to correspond with the bottom-left side of the texture so we use the (0,0) texture coordinate for the triangle's bottom-left vertex. We specify 3 texture coordinate points for the triangle. The following image shows how we map texture coordinates to the triangle: Texture coordinates start at (0,0) for the lower left corner of a texture image to (1,1) for the upper right corner of a texture image. Retrieving the texture color using texture coordinates is called sampling. Texture coordinates range from 0 to 1 in the x and y axis (remember that we use 2D texture images). Fragment interpolation then does the rest for the other fragments. Each vertex should thus have a texture coordinate associated with them that specifies what part of the texture image to sample from. In order to map a texture to the triangle we need to tell each vertex of the triangle which part of the texture it corresponds to. Next to images, textures can also be used to store a large collection of arbitrary data to send to the shaders, but we'll leave that for a different topic.īelow you'll see a texture image of a brick wall mapped to the triangle from the previous chapter. Because we can insert a lot of detail in a single image, we can give the illusion the object is extremely detailed without having to specify extra vertices. A texture is a 2D image (even 1D and 3D textures exist) used to add detail to an object think of a texture as a piece of paper with a nice brick image (for example) on it neatly folded over your 3D house so it looks like your house has a stone exterior. What artists and programmers generally prefer is to use a texture. This takes up a considerable amount of extra overhead, since each model needs a lot more vertices and for each vertex a color attribute as well. However, to get a fair bit of realism we'd have to have many vertices so we could specify a lot of colors. We learned that to add more detail to our objects we can use colors for each vertex to create some interesting images.

Java lwjgl how to resize vao

JAVA LWJGL HOW TO RESIZE VAO CODE

There are other resources though that cover this, take a look at this. There are various different methods depending on your target OpenGL version. If you perform frustum culling at any time, I would advise you to only check for chunks and not every single block, since it would probably be overkill and only result in a performance loss compaired to rendering a few blocks that might be outside of the view frustum but inside a chunk that touches the view frustum.Īlso it is really bad performance-wise to render every block with a seperate draw call. A possibility is that every surrounding block is checked if a specific block gets changed in any form (in Minecraft this is referred to as block updates). This shouldn't be done during every render call, you should only perform such checks if they are necessery. Those which are completely enclosed shouldn't be rendered as they are not visible anyways. You can check every block if it is exposed to air (=no other block) on any side or completely enclosed. Is there an amazingly helpful culling/optimization technique I should know about? I still haven't implemented frustum/occlusion culling. The FPS improved a little, but only by 1-2 FPS. It generated a 10x10 world and doesn't crash, but it runs at only 5 FPS, sometimes less. I found out that there was an infinite loop in the generation process, so I fixed that. It continued to lag and eventually crashed, so I tried to see if it was a problem with the terrain generation. I figured it was because I kept binding and unbinding the same VAO for every block, so I changed that because every block uses the same VAO.

JAVA LWJGL HOW TO RESIZE VAO CODE

In order to tidy up our code a little bit let’s create a new class called Mesh which, taking as an input an array of positions, creates the VBO and VAO objects needed to load that model into the graphics card. The resulting terrain is satisfyingly smooth and even, but the FPS decreases.Īt first I couldn't create a 10x10 world without crashing. In this chapter we will continue talking about how OpenGL renders things. After the smoothing algorithm finishes its task, there are about 1200 cubes. The terrain was initially too rough and uneven, so I created a smoothing algorithm and allowed for the generation of hills.īefore the smoothing algorithm does its job, there are about 900 (+/- 100) cubes. My world generation algorithm is similar to the Diamond-Square algorithm. If(G元0.glCheckFramebufferStatus(G元0.GL_FRAMEBUFFER) != G元0.I am working on a game with blocky graphics - similar to Minecraft.

I have been trying to set the current render area to an FrameBuffer then draw the Frame Buffer larger on the window. The image below shows what I am trying to achieve. I am basically trying to take a small area (example 100x177) and draw it 9 times the original size while still keeping the nearest neighbor. I am going for a retro type of feel for my game and I believe that this would help with that. I am having a little issue with my game trying to get the screen to draw a ton larger.

I can fly

During the past few days, I've made plenty of progress on my Java graphics engine:

I found and fixed a texture-loading bug. Due to a logic error in a pair of nested loops, image pixels (stored in row-major order) were being loaded in column-major order. Previously, I'd worked around the bug by swapping texture coordinates during mesh generation. (e96d47a)

I ported an octasphere mesh generator from my Heart project. (8ca7adf) There are nine-and-sixty ways to generate spherical meshes; octaspheres are my favorite because they work well with textures. The work exposed wrinkles in my engine's support for procedural generation of meshes, which I ironed out.

I added an option to flip the Y-axis of images loaded for use in textures. (cb345a9) In the Y-up realm of 3-D graphics, the Y coordinate usually increases toward the top of an image, whereas in 2-D graphics Y usually increases toward the bottom of an image. This leads to endless confusion. From my experience with JMonkeyEngine, I know "flipY" is a valuable option to have!

The tutorial my engine is based upon provides a Z-up 3-D model and implements a Z-up camera. For compatibility with other projects, I want a Y-up camera. I developed a simple mechanism for rotating a 3-D mesh during the load process. My engine transitioned from Z-up to Y-up at 8f7e244.

I added a Camera class to convert eye location, view direction, field-of-view, and near/far clipping planes into coordinate-transform matrices.

I added a subsystem to manage user input, such as keyboard, mouse, and trackpad. Luckily this isn't my first LWJGL rodeo, so I didn't have to design the subsystem from scratch.

Bottom line: I can fly through the test scene using keyboard and mouse input.

The collision logic between the Ball and the two EdgeShapes works, but collision between the Ball and anything else in the Box2D world crashes the program.

skeletal animations via raft's Bones API The Box2D world uses two separate EdgeShapes as sensors for incrementing a score variable upon collision with the Ball (view attached image).

I wrote sat collision detection system for my game engine just in 1 hour. Those boxes can be rotated to any direction so it can easily beat any AABB system. You can rate examples to help us improve the. You can easily check collision between two boxes. These are the top rated real world Java examples of extracted from open source projects. There is no need for an extra library for collision detection or a seperate GUI package to replace Swing/AWT. I recommend Separating Axis Theorem (SAT).

And what is a Vertex Buffer? A Vertex Buffer is another data structure that packs all the vertices that need to be rendered, by using vertex arrays, and makes that information available to the shaders in the graphics pipeline. And how do you describe a point in a 3D space? By specifying its x, y and z coordinates. But, what is a vertex? A vertex is a data structure that describes a point in 2D or 3D space. The rendering starts taking as its input a list of vertices in the form of Vertex Buffers. The following picture depicts a simplified version of the OpenGL programmable pipeline: In this model, the different steps that compose the graphics pipeline can be controlled or programmed by using a set of specific programs called shaders. OpenGL 2.0 introduced the concept of programmable pipeline. The graphics pipeline was composed of these steps: Thus, the effects and operations that could be applied were limited by the API itself (for instance, “set fog” or “add light”, but the implementation of those functions were fixed and could not be changed). The programmer was constrained to the set of functions available for each step. This model employed a set of steps in the rendering process which defined a fixed set of operations. First versions of OpenGL employed a model which was called fixed-function pipeline. The sequence of steps that ends up drawing a 3D representation into your 2D screen is called the graphics pipeline.

Modern OpenGL lets you think in one problem at a time and it lets you organize your code and processes in a more logical way. It is actually simpler and much more flexible. Let me give you an advice for those of you that think that way. You may end up thinking that drawing a simple shape to the screen should not require so many concepts and lines of code. If you are used to older versions of OpenGL, that is fixed-function pipeline, you may end this chapter wondering why it needs to be so complex. In this chapter we will learn the processes that takes place while rendering a scene using OpenGL.
