Environment Map

The Environment map use two components, both optional.

Cube Map - This generates a 3 dimensional image projected surround the center of the drawing at an infinite distance.

Background - This generates a virtual image which is used to generate background imagery in reflective materials.

PARAMETERS

• Cube Map File Name – Name and Location of the Cube image.
• Cube Map Projection Type – Type of the environment to project.
  • SPHERICAL – Environment mapping type for The source image must be a latitude / longitude spherical map. The (u,v) = (0,0.5) texture map point intersects the X axis of the cube map; the (u,v) = (0,1) texture map point intersects the Z axis of the cube map.
  • CYLINDRICAL – Environment mapping type for The source image is wrapped as a cylinder to define the cube map. The cylinder axis is aligned with the Z axis of the cube map. The (u,v) = (0,0.5) point is mapped along the X axis of the cube map.
  • HEMISPHERICAL – Environment mapping type for The source image must be a latitude / longitude hemispherical map. This is similar to the ENV_SPHERICAL mapping considering only the part of the map above the line of horizon. The (u,v) = (0,0) texture map point intersects the X axis of the cube map; the (u,v) = (0,1) texture map point intersects the Z axis of the cube map.
• Cube Map Size – Size in pixels of the cube map faces (must be power of two).
• Cube Map Border Color – Border color of the source image.
• Cube Map U Wrap Mode –U wrap mode of the source image.
  • REPEAT – Repeat the texture pattern out of the texture's limits.
  • MIRRORED

  • RGBA DXT1 – Compressed image format (lossy). Uses one bit for alpha values. It is the largest compressed form along with RGB DXT1
  • RGBA DXT3 – Compressed image format (lossy). Uses a better encoding for alpha values. Uses more memory than RGBA DXT1
  • RGBA DXT5 – Compressed image format (lossy). Uses the best alpha encoding that is available for these compressed formats. Uses the same memory amount as the RGBA DXT3
  • RGB DXT1 – Compressed image format (lossy). It is the largest compressed form along with  RGBA DXT1.
