Ah thanks for the tip !
I'm indeed using OpenGL ES 2.0, but I'm using it on desktop with a GeForce GTX 260 so maybe there's a way to use it anyhow.
However it doesn't list the pixel_buffer_object...

Hi,

With OpenGL you can do asynchronous texture transfer using a PBO, as described here: http://www.opengl.org/registry/specs/ARB/pixel_buffer_object.txt


glGenBuffers(1, &texBuffer);...

Replying to myself:
1/ Yes
2/ No

A google engineer who has worked on Chrome GPU acceleration is talking about it here:

And the...

Hi,

I'm a little lost on how to create a float texture, between OpenGL 2.0 and OpenGL ES 2.0...


I used to do this on OpenGL:



glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA32F, width, height,...

implementing seamless tiling in fragment shader sounds extreme, it requires providing 9 textures unit (main texture+4 borders+4 corners) and a bit of math in the shader. Just to have some tiling.
...

I just discovered the border parameter in glTexImage2D which I find very useful for my needs (tiling a very large -4096x16384- texture in tiles of 2048x2048), and its associated GL_CLAMP mapping...

On the CPU side I can't (don't wan't to) cut my large array in 16 arrays, it would not make sense anymore as for the various process which are applied to it.
I've been told I could use...

Hello,

I have a very large (let's say 8192x8192), dynamically generated texture array on the CPU side. Part of the data is updated each time the user does an action.
Is there a simple way to...

thanks !

Hello,

Is there a tool/database to know what extensions are supported on a given GPU ?

Thanks

excellent, thanks for the numbers !

Ah, awesome ! So I don't have to write a streaming engine (I'm not coding a game, so automatic swapping would be good enough).

How can I be sure all GPUs have this function ? Is the official name...

Hello,

-What will happen if I upload textures to the VRAM beyond the remaining space ?
Like uploading height 2048*2048BGRA8 textures on a 128MB GPU: what will happen on 7th/8th texture uploaded ?...
