map_colours_to_sphere

map colours from a volume onto a spherical surface object

map_colours_to_sphere src.obj src.mnc dest.obj

DESCRIPTION

map_colours_to_sphere maps colour values from a MINC volume onto a spherical surface object. The source surface src.obj defines the geometry, and the volume src.mnc provides the colour or intensity data. The resulting coloured sphere is written to dest.obj.

For each vertex on the destination sphere, the program samples the volume at the corresponding position derived from the source surface and assigns the resulting colour. This is useful for visualizing volumetric data on a standardized spherical representation of the cortical surface.

EXAMPLES

map_colours_to_sphere cortex.obj t1.mnc sphere_coloured.obj
