Section : 3G
NAME"glEvalPoint1, glEvalPoint2 − generate and evaluate a single point in a mesh
C SPECIFICATIONvoid glEvalPoint1( GLint i ) void glEvalPoint2( GLint i, GLint j )
PARAMETERSi Specifies the integer value for grid domain variable i. j Specifies the integer value for grid domain variable j (glEvalPoint2 only).
DESCRIPTIONglMapGrid and glEvalMesh are used in tandem to efficiently generate and evaluate a series of evenly spaced map domain values. glEvalPoint can be used to evaluate a single grid point in the same gridspace that is traversed by glEvalMesh. Calling glEvalPoint1 is equivalent to calling \f7
glEvalCoord1( icdotDELTAu~+~u1 );
where DELTAu~=~(u2-u1)/n and n, u1, and u2 are the arguments to the most recent glMapGrid1 command. The one absolute numeric requirement is that if i~=~n, then the value computed from icdotDELTAu~+~u1 is exactly u2. In the two-dimensional case, glEvalPoint2, let DELTAu~=~mark(u2-u1)/n
DELTAv~=~mark(v2-v1)/m,
where n, u1, u2, m, v1, and v2 are the arguments to the most recent glMapGrid2 command. Then the glEvalPoint2 command is equivalent to calling \f7
glEvalCoord2( icdotDELTAu~+~u1, jcdotDELTAv~+~v1 );
The only absolute numeric requirements are that if i~=~n, then the value computed from icdotDELTAu~+~u1 is exactly u2, and if j~=~m, then the value computed from icdotDELTAv~+~v1 is exactly v2.
