OK, for the moment, let's ignore the possibility of explicit uniform location and assume that the compiler has carte blanc to assign uniform...

Of course they don't work. `glVertexAttribPointer` can only feed floating-point attributes. Thus, whatever type you pass will be converted into a...

This doesn't make sense. Uniform locations are assigned at link time, so this is a link-time-only issue. There are no performance implications at...

Since you want the vertex attribute to be an integer in the shader you'll want glVertexAttribIPointer (notice the "I"). On a quick glance the...

Ah I see what you're saying, thanks.

... What are you talking about? I was the one who suggested that you rotate it 6 degrees every 1/30th of a second. I didn't say that it was wrong. ...

I ran into this numerous times, albeit during some rapid prototyping which resulted in code which should never make anywhere else - and it worked...

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)...
