Texture Maps

• FreeImage library used for texture loading (click for formats).
• Transparency supported (with user controlled global 'alpha_mode').

---

Texture map table 'np_texture' keeps track of the files and attributes. It is linked (foreign keys) from both the models and node tables.

3D Models Texture File Search Order:

• First it tries the path specified in the 3D models file.
• Then it checks if the texture is in the same folder as the models file.
• Lastly, it searches the default 'usr/global/images' texture folder.

Texture Table:

• np_texture_id table keeps track of the texture files.
• parent_id specifies the multi-texturing hierarchy.
• meta_id external metadata, such as cropping, timecode, color, etc.
• cat asset category is 0 for images, 1 for video, 2 for GLSL....
• name of the file.
• path location of the texture.

Only one texture map per 3D models file (at this time).

np_meta_id table for both native and external metadata.

• type default = 0 for an image file, 1 for video, 2 for GLSL shader.
• crop_min and crop_max XY will trim the texture edges.
• translate XYZ positions the texture.
• rotate XYZ orients the texture.
• scale XYZ sets the size.
• tiling default = 1 repeats XY, 2 for X only, 3 for Y only and 0 for none.
