I'm developing a software like 3d paint using coin3d.
(coin3d 3.0, SoQt 1.4.1, Qt 4.3.1)
In this software, a vertex which user selects with mouse is colored.
The speed of mouse picking (detect vertex id) and setting a color to the selected vertex is fine
But speed of redrawing is slow even if I use "render()" function of ExaminerViewer expressly after specifying color.
It takes 1.5 - 2.0 seconds.
I think it depends on the number of vertex.
(263112 vertices and 526204 polygons)
Because it is very fast in case of using very low polygon model (ex. cube which has 12 triangle meshes).
Does anyone know good techniques for speeding up?
Thanks in advance
