Paint

Paint

Paint on a 3D model is called a "Texture".

Textures are images which are applied to triangle surfaces as paint or color. Textures are also useful for other special effects such as lighting, transparency and reflection.

Modern 3D graphics systems can draw many textures onto a single triangle contributing a variety of color, lighting and special effects resulting in extremely high detail.

3D Kit Builder

Here is our example model with no lighting and no "paint". These triangles have a white color so we see a white silhouette shape of the object. Lighting and Textures give objects depth and color detail that gives them a realistic appearance.

"Unpainted" model (no lighting or textures)

To remove the Paint from our example 3D Kit Builder model use the following Display options which are available when you finish building your 3D model kit:

Display EffectSetting

Wireframe

OFF

Texture (Paint)

OFF

Transparency

OFF

Lighting

OFF

Lighting Normals

OFF

Reflection

OFF

Mirroring

ON

Points

OFF

Triangles

OFF

Then we turn on Texture (Paint) to show the model as "painted".

"Painted" model (no lighting or transparency)

Turn the "Texture (Paint)" Display option ON to re-apply textures onto the model surfaces.

Display EffectSetting

Texture (Paint)

ON

To paint these images onto triangle surfaces we need to include additional image location information at each point (or corner) on all "texture mapped" triangle. This information is commonly known as "U.V.'s" (u-vee's).
