Reference Talk:UV Mapping

• Additional uv mapping supported objects.

Supported Objects

Surface mapping is currently defined for the following objects:

• bicubic_patch : UV coordinates are based on the patch's parametric coordinates. They stretch with the control points. The default range is (0..1) and can be changed.
• box : the image is wrapped around the box, as shown below.
• lathe, sor : modified spherical mapping... the u coordinate (0..1) wraps around the y axis, while the v coordinate is linked to the object's control points (also ranging 0..1). Surface of Revolution also has special disc mapping on the end caps if the object is not 'open'.
• mesh, mesh2 : UV coordinates are defined for each vertex and interpolated between.
• lemon : cylindrical mapping wrapped around the axis from the base point to the cap point.
• ovus : spherical mapping centered near the center of mass of the ovus (moving from one sphere to another as the ratio of radius progresses).
• parametric : In this case the map is not taken from a fixed set of coordinates but the map is taken from the area defined by the boundaries of the uv-space, in which the parametric surface has to be calculated.
• sphere : boring spherical mapping.
• torus : The map is taken from the area <0,0><1,1> where the u-coordinate is wrapped around the major radius and the the v-coordinate is wrapped around the minor radius.

lemon's detail

the discs on each side get 0.25 each the spindle part gets 0.5 of the range.

[0 to 0.25 base disc, from center to border] [0.25 to 0.75 spindle from base to apex] [0.75 to 1.0 apex disc, from border (0.75) to center]

You might want to rephrase the above for native speaker.

Supported Objects Updates

Unsure if we should call these bug fixes ... which is my guess since there was a previous implementation(s). Comment and/or note below and I'll update accordingly

My bad ... after re-reading I see that cone and cylinder are indeed New. I'd appreciate any notes that maybe offered before I make the change
