PHIGURE C REFERENCE MANUAL - 3D SURFACE OF A 3D MESH

3D SURFACE OF A 3D MESH

tisosurface

CALL SEQUENCE

void tisosurface (struct_id, mesh, data, iso_value)

INPUT PARAMETERS

Pint	struct_id;
Tmesh3D	*mesh;
Tscalar3D_data	*data;
Pfloat	iso_value;

ARGUMENTS

struct_id: Structure identifier.
mesh: 3D mesh
data: Value for each node of the mesh
iso_value: 3D surface value

EFFECT

This function creates a 3D surface out of a 3D mesh. This surface may be lighted using standard PHIGS lighting facilities. Refer to PHIGURE sample programs to see how to light this surface.

If applied to a non-structured mesh, this mesh must be well oriented to create a well oriented 3D surface (See non-structured mesh part and orientation constraints). If a mesh element does not have the good orientation then part of the 3D surface crossing this element will not have the good orientation. In this case lighting won't be rendered correctly.
