GsoC: OpenGL viewport optimization!

Hey Guys,

I did a head to head with 2.49 vs the 2.5 Viewport optimization build (r22296)

Its nothing fancy but i thought some of you might like to check it out any way.

I used a 2 million tri mesh to do the test and the captures were all recorded in real time.

Its converting over at vimeo right now but it should be finished in 25 mins or so.

:slight_smile:

edit

Its finished uploading but i think i must have exported it incorrectly as its been sped up by loads :S

I recommend that you download the MP4 until i can get it fixed

Gah! Tried a cube, went into editmode - its just a transparent cube - no vertices. subdivide a couple of times, and then suddenly weird artefacts all around the 3d view. I can post a picture when I come home. My card is Radeon X550.

I’m having the same problem. Earlier builds worked fine for me. Maybe changing the draw type helps (didn’t help for me but nevermind). You can find the draw type in the user preferences.

The Video is all fixed now :slight_smile:

Sorry about that :stuck_out_tongue:

Lukas will wrap up his work on faster Mesh draw (FBO), needs people with ATI to help

I have a ATI graphic card on Windows XP. PM me or write here how I can help.

Same here, althought i don’t need to subdivide, distortions start when moving the viewport. ATI HD 2600 XT with Catalyst 9.8 on WinXP SP3 using this build http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1091

what a strange problem on the Ati cards but anyway a really sweet project, great work! :slight_smile:

Blender needs an “ATI sucks” disclaimer…I always was an ATI guy, but then I switched last year and bam…never going back…I hate those drivers.

Well acutally everything worked fine for me so far with my graphics card. But this is definitely some serious issue. Probably just some code fixes that need to be done?

I had a short chat with him on irc, I have an ATI card and had problems, he doesn’t have the hardware to test it himself so… well it’s hard to know what specifically is going wrong.

A new build is available. Due to nicholasbishop the edit mode disco inferno is over now.

Works perfect! Thanks a LOT :). And I’m still wondering for probably 2 or 3 months … how do I know how many vertices are in my scene :evilgrin:? (Why am I asking I won’t get an answer anyway xP)

Tried this build, but it crashes when loading.

Using WinXP, Intel Graphics 830M.

This build seems a bit buggy for me (specs in my sig) … prone to crashing while sculpting. There’s also some kind of ‘lag’ in response that registers Button window clicks as 3D view operations when moving from one to the other at my usual speed (starts to move the mesh when all I meant to do was change brushes).

I looked around a bit after your mention of this previously … doesn’t seem to be possible yet.

Sigh intel graphics. Could you please test both of those .B25.blends here http://drop.io/1lrrgln

There ya go:

2.5: Restored statistics in the info header.

Tried both blend files. Still crashes.

Is it safe to assume that Viewport acceleration is a failed GSOC?

Wow, why the negativity? Even if this was to be only enabled at build time for a single brand of graphics card it would still be a benefit.

It’s working for me! So why should you assume it is a failed GSOC??
