Common properties of all textures:

● Pixel format:

Possible settings are RGB 24-bit or RGB 32-bit. With the latter, its alpha channel

determines transparency at the same time.

● Mapping type:

Determines how the texture is applied on the object. Since objects are three dimensional

geometries and a texture like wrapping paper is a planar rectangle, there are several

ways in which the texture can wrap around the object

Possible values:

Predefined:

Most 3D modellers store so-called texture coordinates for each vertex of each polygon of

each model. These two-dimensional coordinates define which pixel of the texture bitmap

belongs to the given vertex. OpenGI is able to interpolate between these coordinates set

for the vertices.

In Nemo each Primitive, and possibly all imported 3D models have predefined and stored

texture coordinates. Text objects, on the other hand, do not have this property.

Generated:

Here texture coordinates are generated by OpenGl according to the value set for

Mapping. Possible values:

Object Linear: It applies the texture using planar projection on the object, using the local

coordinate system of the object. If the object moves, the texture moves with it.
