NAME

GDX_RECT_MESH - Rectangular Surface Point Mesh

GENERAL DESCRIPTION

The GDX Rectangular Surface Point Mesh (GDX Rectangular Mesh) entity is a collection of linear approximation points that form a regular (rectangular) UV grid on a GDX surface entity. This is the default entity for linear approximation of GDX surface entities for faceted approximation. This entity is also used to define the initial projection grid for the projection of curves and/or points to a GDX surface.

FIELD DESCRIPTIONS

NUM_U_POINTS

The number of points in the u direction.

NUM_V_POINTS

The number of points in the v direction.

MESH_POINTS

Array, dimensioned to [NUM_U_POINTS][NUM_V_POINTS][3], containing values that define the model space points of the GDX Rectangular Mesh.

MESH_PARMS

Array, dimensioned to [NUM_U_POINTS][NUM_V_POINTS][2], containing values that define the parameter space points of the GDX Rectangular Mesh.

RESTRICTIONS
