I'm using XNA 4.0 and I need 10k more draw cube(i don't need lighting and texture color.only just cube color).

I found hardware instance cube. But this is not possible. Because all cube is diffent.

how can many cube very fast draw ?



ps. current performance 1k cube(not texture image,only color) 15fps...-_-;

What's different about the cubes? Hardware instancing may still be possible.

It appears that the gentleman thought C++ was extremely difficult and he was overjoyed that the machine was absorbing it; he understood that good C++ is difficult but the best C++ is well-nigh unintelligible.

WIth hardware instancing, drawing some thousand cubes should be almost trivial, unless drawing the cubes eat take a lot of pixel fill rate.

What is the difference between each cube? Hardware instancing doesn't exclude differences with the objects, for example all the objects have typically a different transformation, so using the same idea, they can have different color for example, or even different texture.

Cheers!

Well size is something that you can express with the transformation matrix, and since all the cubes already need one to have different position and orientation, you'll just need to scale the transformation matrix to produce smaller and bigger cubes.

Yes,

Googling "XNA 4.0 instancing" gives pretty good results for the described problem.

Yes, that kind of chart is possible to do with instancing. Just use non-uniform scaling. That is, scale more at the y/z-direction.

Cheers!
