Re: [Pharo-project] Saga of trying to integrate IDE with OpenGL continuesRe: [squeak-dev] Re:NativeBoost and NBOpenGL on Mac?

well, one of the ideas is to use fallback display in case of openGL error(s). And render not to GL context but to bitmap. Then you can actually use debugger to debug GL calls step by step without interfering with GL stack/state. Another approach would be to create a separate GL context and use it for debugger. But then you need to keep an eye for switching active contexts at right moment.

Keep going. I would love to have opengl well integrated. Alexandre On 16 Jan 2012, at 23:44, Lawson English wrote:

That is really Igor's job, not mine. I'm just throwing together stuff using the original Croquet OpenGL calls and making videos of what I'm doing. L. On 1/17/12 10:31 AM, Alexandre Bergel wrote:

BTW, the video I mentioned a day or so ago now has 90 views, in only 3 days. Just so much I'd tried to get this all running under Pharo. I guess 32-bit Pharo on 64-bit Debian is not a good base for running OpenGL stuff ;-(

Doh, I never even tried to run it on Pharo. :-( The croquet opengl package won't load or is it something specific to my stuff? L. On 1/17/12 11:26 PM, Friedrich Dominicus wrote:

sigh, I'm getting disk access constantly when my little GUI opengl thingie runs. The max FPS is 10ish. Package is: OpenGL-Tutorial-LDE.32 in monticello repository: 'http://croquet-src-01.oit.duke.edu:8886/Contributions' suggestions? Thanks. L.
Apparently there was a glError that I wasn't catching, so the disk address issue has gone away: the Baloon3D plugin was logging errors I didn't catch. However, I'm not sure how to efficiently blit GUI updates to the gl texture, so suggestions appreciated. Looking at the Squeak3D.log file, it seems to me that Baloon3D already has access to all the values that Igor is using to setup his NBOpenGL and GLCanvas packages. Would it be better to leverage that as a cross-platform initialization for OpenGL instead of another plugin?

My point is following: the more logic you put into VM code (plugin etc), the more limited you are. Because instead of deciding by yourself, what you prefer and what not, someone else deciding for you. I hate constraints, especially in such performance sensitive areas as graphics, where changing a single flag value could mean 10x difference in performance (if not 100x). If we ever need some helpers from VM side is mainly glue code to obtain some handles to resources (like main window handle, etc). But all levers of controls should be at language side, VM should serve as a dummy servant who has no idea what you going to do and just strictly following your orders.
