AxisAngleMap
Overview
AxisAngleMap takes an input vector and rotates it about an axis.
When rotating surface normals for non-photorealism, input and output spaces should be set to “render.”



Attribute Reference
General attributes
angle
Float bindable
default: 0.0
the angle of rotation in degrees
axis_space
Int enum
2 = “world” (default)
4 = “object”
the space of the axis to rotate about
input_space
Int enum
0 = “render” (default)
1 = “camera”
2 = “world”
3 = “screen”
4 = “object”
the space to transform from
input_vector
Vec3f bindable
default: [ 0, 0, 1 ]
input vector to be rotated
output_space
Int enum
0 = “render” (default)
1 = “camera”
2 = “world”
3 = “screen”
4 = “object”
the space to transform the resulting vector to
rotation_axis
Vec3f bindable
default: [ 0, 1, 0 ]
axis to be rotated around
Examples
local attrmap = AttributeMap("attrmap") {
-- shading normals
["map_type"] = 3,
}
-- rotate about world space
-- shading normals should remain perpendicular to screen
local axisanglemap0 = AxisAngleMap("axisanglemap0") {
["input_vector"] = bind(attrmap),
["input_space"] = 0,
["rotation_axis"] = Vec3(0,1,0),
["axis_space"] = 2,
["angle"] = 50,
["output_space"] = 0,
}
