The rgl Package - NexTag Supports Open Source Initiatives

32 qmesh3d
Value
Each primitive function returns the integer object ID of the shape that was added to the scene. These
can be passed to rgl.pop to remove the object from the scene.

qmesh3d
3D Quadrangle Mesh objects
Description
Usage
3D Quadrangle Mesh object creation and a collection of sample objects.
Arguments
qmesh3d(vertices, indices, homogeneous = TRUE, material = NULL, normals = NULL)
cube3d(trans = identityMatrix(), ...) # cube object
oh3d(trans = identityMatrix(), ...) # an 'o' object
dot3d(x, ...) # draw dots at the vertices of an object
## S3 method for class 'qmesh3d':
dot3d(x, override = TRUE, ...)
wire3d(x, ...) # draw a wireframe object
## S3 method for class 'qmesh3d':
wire3d(x, override = TRUE, ...)
shade3d(x, ...) # draw a shaded object
## S3 method for class 'qmesh3d':
shade3d(x, override = TRUE, ...)
x
a qmesh3d object (class qmesh3d)
vertices 3- or 4-component vector of coordinates
indices 4-component vector of quad indices
homogeneous logical indicating if homogeneous (four component) coordinates are used.
material material properties for later rendering
normals normals at each vertex
trans transformation to apply to objects; see below for defaults
... additional rendering parameters
override should the parameters specified here override those stored in the object?
