In Topic: MinGW64 and GLES2 emulator?

Today, 08:53 AM

VBO's are not supported by default in OpenglES 2.

It's really frustrating, on some devices you HAVE to use VBO's, on others they are not available.

Khronos really screwed up on the spec for ES2, I think they have done a better job on ES3, but I don't have any devices that support it yet. :(

From talking to people, it seems that Khronos were scared that none of the manufacturers would support it if they put too many things in the spec, but the result is that ES2 is crippled.

I have a compiler flag USE_VBO and have two versions of my rendering code.

I have enough distractions, skype goes off all times day and night, email is always on, mobile phone, wife, kids, ...... ahhhhhh

skype is incredibly useful, you can share documents, talk with your mouth instead of your fingers, send files, even video conference. That is what I call a useful tool.

I have a contact group setup for technical queries, normally I can get feedback day or night, and I help people out whenever I am online. It just works.

twitter..... well I guess it's just me, but I feel it's useless clutter.

Why the hell would you twitter?

Most of the stuff I have seen is complete rubbish.

From broadcom .....





There isn't really a distinction between system and video RAM, that's PC thinking, we only have a single unified memory system on our STBs.



The real difference between the two methods is one references the data by pointer while the other copies and processes the data every frame.

Sounds like they do some sort of processing on the vertex buffer before the GPU can handle it.

I'm going to go and see the graphic team next week so will be able to get more detail on what happens at the hardware level then.

I'll report back when I get more data.

:D :D :D

Thank the force for that

So going from vertex arrays to VBO's gave a 375fps increase.

Man that's weird
