primitiveQuad operation

Syntax

primitiveQuad()

primitiveQuad(width, length)

Parameters

• width (float)
  Width of the quad.
• length (float)
  Length of the quad.

Description

The primitiveQuad operation inserts a quad geometry into the scope of the current shape.

• If no width and length is given the bounding box coincides with the scope. Zero scope sizes are handled the same way as in the i operation.
• If dimensions are specified the quad is positioned in the xz center of the scope lying on y=0.

If one scope size is zero while the 2 other sizes are not zero the quad will be inserted with respect to the plane defined by the valued scope sizes.

The quad has texture coordinates on the first texture layer (COLORMAP).

Examples

	Lot--> rotateScope(0, 0, 90) // scope.sx is 0 primitiveQuad() texture("builtin:uvtest.png") The inserted quad is fit into the current scope yz dimension.
	Lot--> rotateScope(0, 0, 90) // scope.sx is 0 primitiveQuad(10,20) texture("builtin:uvtest.png") The inserted quad has a width of 10, a length of 20 and is positioned in the yz center.

primitiveDisk operation

Syntax

primitiveDisk()

primitiveDisk(nVertices)

primitiveDisk(nVertices, radius)

Parameters

• nVertices (float)
  Number of vertices at the boundary of the disk. There must be at least 3 vertices. The default value is 16.
• radius (float)
  Radius of the disk.

Description

The primitiveDisk operation inserts a disk geometry into the scope of the current shape.

• If no radius is given the bounding box coincides with the scope. Zero scope sizes are handled the same way as in the i operation.
• If radius is specified the disk is positioned in the xz-center of the scope lying on y=0.

If one scope size is zero while the 2 other sizes are not zero the disk will be inserted with respect to the plane defined by the valued scope sizes.

The disk has texture coordinates on the first texture layer (COLORMAP).

Examples

	Lot--> rotateScope(-90, 0, 0) // scope.sz is 0 primitiveDisk() texture("builtin:uvtest.png") The inserted disk has 16 vertices and is fit into the current scope xy dimension.
	Lot--> rotateScope(-90, 0, 0) // scope.sz is 0 primitiveDisk(8,10) texture("builtin:uvtest.png") The inserted disk has 8 vertices, a radius of 10 and is positioned in the xy center.

primitiveCube operation

Syntax

primitiveCube()

primitiveCube(width, height, depth)

Parameters

• width (float)
  Width of the cube.
• height (float)
  Height of the cube.
• depth (float)
  Depth of the cube.

Description

The primitiveCube operation inserts a cube geometry into the scope of the current shape.

• If no width, height and depth are given the bounding box coincides with the scope. Zero scope sizes are handled the same way as in the i operation.
• If dimensions are specified the cube is positioned in the xz-center of the scope lying on y=0.

The cube has texture coordinates on the first texture layer (COLORMAP).

Examples

	Lot--> primitiveCube() texture("builtin:uvtest.png") The inserted cube is fit into the current scope. The scope's zero size is modified relative to the average of the two non-zero sizes.
	Lot--> primitiveCube(10,15,20) texture("builtin:uvtest.png") The inserted cube has a width of 10, a height of 15, a depth of 20 and is positioned in the xz center.

primitiveSphere operation

Syntax

primitiveSphere()

primitiveSphere(sides, divisions)

primitiveSphere(sides, divisions, radius)

Parameters

• sides (float)
  Number of subdivisions along latitude of the sphere. There must be at least 3 sides. The default value is 16.
• divisions (float)
  Number of subdivisions along longitude of the sphere. There must be at least 2 divisions. The default value is 16.
• radius (float)
  Radius of the sphere.

Description

The primitiveSphere operation inserts a sphere geometry into the scope of the current shape.

• If no radius is given the bounding box coincides with the scope. Zero scope sizes are handled the same way as in the i operation.
• If radius is specified the sphere is positioned in the xz-center of the scope lying on y=0.

The sphere has texture coordinates on the first texture layer (COLORMAP).

Examples

	Lot--> primitiveSphere() texture("builtin:uvtest.png") The inserted sphere has 16 sides, 16 divisions and is fit into the current scope. The scope's zero size is modified relative to the average of the two non-zero sizes.
	Lot--> primitiveSphere(8,4,10) texture("builtin:uvtest.png") The inserted sphere has 8 sides, 4 divisions, a radius of 10 and is positioned in the xz center.
