Hello?
I love pocket soccer game very much.
I think Single and Tournament ‘s artificial intelligence should change more hardly. and computer’s attack and defend way should improve better in a hard way. It’s too easy.
I’m waiting for world class ver much
thank you

Comment on Instance culling using geometry shaders by feng

thank for reply. Looking forwards to the article!(though my cards are limited to 3.3~)
By the way, for instancing, if I use crossed billboards for the grass instead of model, then I may still do instancing with attributes divisor or so and draw using one call; or I may just draw points of position(glDrawArrays(GL_POINTS,..), one draw call though), and populate them in the geometry shader. Which one may be better?

Another, for instancing, if i do culling as above,then i may first pass the instance data(position) to the pipeline, then the actual vertices by the 2nd pass. As the count ratio of them is merely 4:1,or at most 12:1, i tended to think the culling pass cost not so little compared to the whole “vertices” sent . or maybe still a gain to cpu culling? is that right or not? thanks

In case you don’t use instancing or the instance count is too small, then it is possible that the delay caused by waiting for the culling pass’s result would be prohibitive.

However, you should know that no actual vertex data is passed to the culling pass so that’s not true that vertex data has to be sent twice as you use only the instance data buffer in the culling pass.

In most cases, actually not the culling pass that takes time but the waiting for the culling results is the one that is rather expensive.

Actually there is a solution for both problems (i.e. for non-instanced data and query result delay) if you use OpenGL 4.2+ and I plan to write a demo that will show this technique, however, the technique presented in this article provides advantages only in case of instanced data and in case the instance count is relatively high.

If not for Instanced data, or, the instance count is not that large, would the method here also be a gain? Compared to culling on CPU, the mass of vertices’ data must be sent almost twice. And it’s after the geometry stage that vertices are automatically culled for the view port. thank you.

Hello Daniel,

really nice nature demos. but i am far from understanding the code.
it would be very nice if you publish a beginner code, just rendering a colored triangle in opengl 3.3

thx in advance
