In Topic: MinGW64 and GLES2 emulator?

Yesterday, 03:19 PM

Thanks for the hint with VBO. I've to regard this and should use ES Arrays in that case. Your Compiler flag is a good idea.

But I think this is not the problem. Same code runs with PVRFrame on 32bit MinGW with VBO's (a version I've implemented last year before I've start with c++11 support).

I've found the Angle library as ES2 emulator and will give it also a try. Also I will check out ES3, I've seen PVRFrame also offers libs for it...

I checked my render data again, anything is correct. I also tried to lock the entire buffer with discard flag, but this solves not the problem.
Finally i've implemented a zero fill of the entire buffer before writing the data to the buffer, now it works. Thanks for your support.

I've checked my values multiple times, they should be correct (I use the same values as base on GL buffers where all is perfect). The offset is allways zero and I use length in bytes... I will try out the zero filling.

Thanks for your detailed informations. If I can't follow your advise with the sections, what is the better way I should go? Should I zero fill the entire buffer before each write call or should I recreate a new one?

I pass first 6 Vertices, at 2nd also six (changed texture) and finally 12 Vertices using same texture as data from first pass. The issue occurs rendering the final content. Each pass has zero offset. I thought the discard flag ensures that the content of the buffer is discard completely.
