Hello,

Testing my commit show two stranges things:
webcam apply does'nt work (black screen) but hot point detection and tracking seem's ok.

but commenting

Code:

raydium_live_texture_mask_name("drawing.tga",1);

in display callback make webcam image appear again.

It's like drawing is no more transparent.

Does this problem is windows specific ?

In other case what appened ?

Appli train_cloud.c faild with skybox texture (not intialised). But sky render was really strange with a cool visual effect. To be tested ... if you want.

Have a nice day
Ouille.

Hello,

line 864 of live.c

Code:

glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,tex->tx,tex->ty,

changing GL_RGB by GL_RGBA make live ok ok again.

Is it correct ?

Have a nice day
Ouille.

Performance issues are back with GL_RGBA texture "uploading" on some hardware. I missed an important point with my previous commit (694) about that, with 24bpp non power of two textures, and (hopefully) completed this with my last commit.

Sorry about that !
