Hey Neil,
thank you so much for sharing clutter-ply, I checked it out an it's amazing.
I could make the monkey example work, and I've been playing with it
with excellent results.
What I couldn't make it work, is applying a texture to any PLY file. I
followed your instructions, tried several models, and textures, and I
always get the model painted with the solid color defined by
cogl_material_set_color4ub.
I used the exact code as you posted, using
texture = cogl_texture_new_from_file ("models/models.png",
COGL_TEXTURE_NONE, COGL_PIXEL_FORMAT_ANY, &error);
I also checked that the texture is loaded successfully.
Any idea on what's wrong? In the COGL reference says that the color
set in cogl_material_set_color4ub will be used when no lighting is
enabled. Could be this the reason?
Thank you!
Marc
