The Lounge What is on Your Mind? Similar Threads: More UNIX and Linux Forum Topics You Might Find Helpful Update Post 303021553 by RudiC on Sunday 12th of August 2018 01:47:10 PM
Brilliant, thank you.
I found an overbalance of the proposals lying in the past, omitting / ignoring recent contributions. Not implying the recent ones are better, but would it be feasible to make distribution of selected threads spread somewhat more evenly?

Hello. I have redesigned our "similar threads" for a more "clean style" in both the desktop view and the mobile view for the forum "show thread".

GLEVALPOINT(3G) 														   GLEVALPOINT(3G)

NAME
glEvalPoint1, glEvalPoint2 - generate and evaluate a single point in a mesh C SPECIFICATION
void glEvalPoint1( GLint i ) void glEvalPoint2( GLint i, GLint j ) PARAMETERS
i Specifies the integer value for grid domain variable i. j Specifies the integer value for grid domain variable j (glEvalPoint2 only). DESCRIPTION
glMapGrid 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 glEvalCoord1( i./u+u1 ); where /u=(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 i./u+u1 is exactly u2. In the two-dimensional case, glEvalPoint2, let /u=(u2-u1)/n /v=(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 glEvalCoord2( i./u+u1, j./v+v1 ); The only absolute numeric requirements are that if i=n, then the value computed from i./u+u1 is exactly u2, and if j=m, then the value computed from i./v+v1 is exactly v2.
