Hi,
I need to clarify some doubts regarding texture size and number of drawables
(Geometry) in a node and its effect on 'draw time'.
For example i've a osg node, with a geode present inside a MatrixTransform.
The geode contains 4 geometries (drawables), each drawable has a diffuse
texture of size 512x512. Now the number of draw calls is 4. (correct me if i'm
wrong). Now i'm converting the four 512x512 textures into single 1024x1024
texture (single material) in photoshop and apply it to the mesh in 3D Software
(blender or 3D Studio Max) and exported it to OSG format. Now the geode in the
osg file contain a single drawable with a single material and texture.
I would like to know whether the four drawables or single drawable will
consume more time to draw.
How is the draw time affected when multiple UV's are applied to the mesh
for the above case.
...
Thank you!
Cheers,
Saravanan
