You should not store the returned array for later use.

For this task, in previous versions of LWJGL, the Slick2D library was commonly used. The first step is to load the image that will be used as a texture.
JAVA LWJGL BYTE BUFFER TO TEXTURE CODE
So let’s start modifying the code base to use textures in our 3D cube. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links. These examples are extracted from open source projects.
JAVA LWJGL BYTE BUFFER TO TEXTURE HOW TO
Therefore the recommended way to use this method is to get the data, and use or modify it immediately. We set up a VBO which will have a texture coordinate for each vertex position. glGetTexImage () The following examples show how to use 11 glGetTexImage (). it no longer points to valid memory) if modifications or uploads happen to the texture after you call this method. Note: The returned array can become invalid (i.e. Java example: NanoSvgTest / - Test set: - Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.307 s. GetRawTextureData does not allocate memory the returned NativeArray directly points to the texture system memory data buffer. If you write to it, you must call the Apply method to upload the texture to the GPU. You can read from and write to the returned array. For example, a 16x8 texture of RGBA32 format with no mipmaps will result in a 512-byte array (16x8x4), or a 128-element array if Color32 is used as a type. Mipmaps are laid out in memory starting from largest, with smaller mip level data immediately following. The data will be whole texture according to its width, height, data format and mipmapCount. I know the examples there are not written in Java, but the basic facts about how to use OpenGL should be very much applicable anyway.This function returns a direct "view" into the texture pixel data as a. I would recommend you look into basic tutorials such as ones on LearnOpenGL. These vertex buffers are associated with so-called vertex arrays which you can use to actually relate your vertex data to certain vertex shader inputs.

This can be done in several ways, modern GPUs and modern OpenGL, versions 3.x and 4.x, prefer to use so-called vertex buffers which reside in memory on the GPU. For such a draw call to work, you need to pass some geometry to OpenGL. What you would need to do is in between these lines issue actual drawing commands, such as glDrawArrays(.) etc. This clears the back buffer (to yellow in your case) and then you immediately present the contents of this back buffer to your window with the glfwSwapBuffers command. In your loop function you do: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) Estos son los ejemplos en Java del mundo real mejor valorados de 11.Texture extrados de proyectos de cdigo abierto. you are never telling OpenGL to render anything. Foremost problem is that you are not issuing any actual OpenGL draw call, i.e. I see several issues and missing things in your approach. This time I tried this code, of couse it doesn't work (I read it on StackOverflow): public class Starter If you want to load an image file and render it, you will need to create a Texture from that data.

The first time, I used Sick, but it was deprecated. Ignore BufferedImage, ignore canvases, ignore every single part of the standard Java library relating to graphics. I have already tried to do it, but got stuck on this same problem: how render text on screen. After some months on libGDX, I chose to make a little java game library based on LWJGL.
