IDLitVisualization::VisToWindow

The IDLitVisualization::VisToWindow procedure method transforms given points from visualization data space to window device coordinates.

Syntax

Obj->[IDLitVisualization::]VisToWindow, InX, InY, InZ, OutX, OutY, OutZ [, /NO_TRANSFORM]

or

Obj->[IDLitVisualization::]VisToWindow, InX, InY, OutX, OutY [, /NO_TRANSFORM]

or

Obj->[IDLitVisualization::]VisToWindow, InVerts, OutVerts [, /NO_TRANSFORM]

Arguments

InX

A vector of input X values (in visualization data space).

InY

A vector of input Y values (in visualization data space). The number of elements of this vector must match the number of elements in InX.

InZ

A vector of input Z values (in visualization data space). The number of elements of this vector must match the number of elements in InX.

InVerts

A [2, n] or [3, n] array of input vertices (in visualization data space).

OutX

A named variable that will contain a vector of output X values (in window device coordinates).

OutY

A named variable that will contain a vector of output Y values (in window device coordinates).

OutZ

A named variable that will contain a vector of output Z values (in window device coordinates).

OutVerts

A named variable that will contain a vector of output vertices (in window device coordinates).

Keywords

NO_TRANSFORM

If this keyword is set, the current transformation matrix is not included in the computation. Setting this keyword is useful when computing selection visual scaling.
