Interestingly, I have never had such problem. Maybe because I'm using object-wrapper which fetches uniform location in the initialization function,...

This example uses vertex and fragment shader: http://fabiensanglard.net/bumpMapping/index.php

I got it :) I did not even have to swap between two textures. I just copy the screen to the scene texture. filters.get(i).filter(scene,...

Totally agree. This has bugged me for years.

Why is this "wrong" to rotate an object 6 degrees each keyframe? It looks fine and works well.

This was not the problem as i tried. You're right, i read and write the same texture! This might be the problem. But, why do i need to swap...

glm.h is the header file of the library. somewhere in your system, probably in /usr/lib, there has to be something like libglm.so or similar, which...

You're simply doing it the wrong way. If you have a single animation that lasts 10 seconds and during that time, you have a 5 360 degree revolutions,...

Sorry, you misunderstand. I can set a single animation to last, say, 10 seconds, and in that 10 seconds I get 5 full revolutions, or 360*5 degrees....

Why do you need keyframes far enough apart that this is necessary? Generally speaking, keyframes should only be at most 1/10th of a frame apart. You...

GL11.glDrawBuffer(GL11.GL_NONE); GL30.glBindFramebuffer(GL30.GL_FRAMEBUFFER, fbo); usePostProcessingTexture(renderer.getSceneTexture(0)); ...

Thanks, a nice implementation has been given to the following link:...

You'll get a faster answer if you read through our Posting Guidelines and rules.

You collect the contour values for a pixel when ever you render the screen (the overhead on the shader is trival but you do need any extra texture...

I was wondering if I selected a different subroutine using dynamic subroutines would a change in instruction rate correspond to a better (worse)...

Thanks for the reply. Just forgot to add glDrawArrays(GL_TRIANGLES,m_nVBO_OffsetPosition, m_tDataPosition.size()); at the end, now it's there but...

I'm using NV PerfKit for a long time, but only the first release (called PerfSDK), that does not support Fermi/Kepler. Version 2.2 was released a...

hi, thats really a strange one. i copy and ran your code. by changing the parameters of glut sphere i was able to change black spot size ... my...

hi, first of all, nice code style ! i am not shure if you just forgot to post it, but after you have set all the attrib pointers and the uniforms...

Remember where I said that it doesn't take an array? That's what I was talking about. It takes a pointer to a single `GLuint`. As previously...

OMG! I am confused :confused: Well, I did understand the first half. But how can I change the number of contour lines? Will Edge detection algorithm...

One more concern, i was using glVertexAttribP4uiv with GL_INT_2_10_10_10_REV. For signed data type, we have to use same API. So i was calling it with...
