I\'m trying to implement texture projection based directly on this example at oZone3d.My environment is OpenGL ES 2.0 on Android 2.2.
I\'m very new to GLSL, but I\'m trying to write convolution kernel with in a fragment shader for image processing.I was able to do this just fine when my kernel was small (3x3) using a constant matrix
just had a simple question about opengl es that I couldn\'t find the answer to. So I am trying to display simple meshes made in blender using oolong3D\'s blenderparse example, but when I import the te
I am trying to load earth.png and place it over a triangle. The image is 256x256. I have followed an online tutorial and played around with this for hours, but the triangle still remains white. Can an
Here is my code. I\'m attempting to draw a simple quadrilateral, and place a checkerboard pattern on both sides of it. I want to allow the user to rotate around this piece with the mouse. Everything w
I\'m developing an UI for a project for school, and I\'ve tried similar methods to scaling my texture as listed here, but here is the issue:

I am working on an app that uses 2D textures to create animated kaleidoscopes. It starts out displaying to an NSOpenGLView. I am adding an option to switch to full-screen mode.
Here\'s my problem. I\'m rendering an orthogonal quad (filling the viewport) before everything (with vertex coloring at each corner), right after I\'m rendering a cube skybox with 6 transparent polyg
