Summary#
Combine small meshes into larger ones where appropriate
Description#
Optimize scene performance by combining small meshes into larger ones where appropriate. Fewer, larger meshes often perform better than many small ones.
Why is it required?#
Higher memory overhead
Slower scene loading
Reduced rendering performance
Examples#
# Not recommended: Many tiny separate meshes
def Xform "TinyMeshes" {
def Mesh "SmallCube_1" {
float3[] extent = [(-0.001, -0.001, -0.001), (0.001, 0.001, 0.001)]
int[] faceVertexCounts = [4, 4, 4, 4, 4, 4]
int[] faceVertexIndices = [0, 1, 2, 3, ...]
point3f[] points = [(-0.001, -0.001, -0.001), ...]
}
def Mesh "SmallCube_2" {
float3[] extent = [(-0.001, -0.001, 0.002), (0.001, 0.001, 0.004)]
int[] faceVertexCounts = [4, 4, 4, 4, 4, 4]
int[] faceVertexIndices = [0, 1, 2, 3, ...]
point3f[] points = [(-0.001, -0.001, 0.002), ...]
}
}
# Recommended: Combined into efficient single mesh
def Mesh "CombinedMesh" {
float3[] extent = [(-0.001, -0.001, -0.001), (0.001, 0.001, 0.004)]
int[] faceVertexCounts = [4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4]
int[] faceVertexIndices = [0, 1, 2, 3, ...]
point3f[] points = [(-0.001, -0.001, -0.001), ...]
