I think its awesome that you try to make a 3d game engine for Pharo. I know its not an easy task by a long mark, its tons of hard work to have something reliable. Thank you for your efforts and if you want a beta tester I will be more than happy to help you.��

Saying that I am highly skeptical . There is a reason why 3d engines rarely become popular in dynamic languages. Performance. Same reason why C/C++dominate 3d graphics and audio synthesis.��

I agree that sending things to GPU will greatly boost performance for Pharo not just for Graphics but for all sort of things. CUDA and OpenCL can be used for loads of different computations and a good modern GPU can offer 8 times the performance of a good CPU.��

On the other hand having a good 3d game engine for Pharo is a thousand times better than not having such a thing at all. So keep rocking :)

I am working on making a video game engine in Pharo. Recently added a FPS counter and recorded some samples: http://youtu.be/-2ida5Q1mbg .

Lets say I was quite surprised, so I have yet a lot more to optimize, but a good trick seems to be making some computation in the GPU.

In this video, I show 6 early examples. The water example is still incomplete, missing reflection/refractions, but it shows what happens when I compute the water waves using a shader in the GPU.

Please, pay a close attention to the FPS count.

BTW, it feels slow because of the screen capture and the tearing is there because I haven't enabled vsync, but I have support for it.
