Tech/LxEngine/Samples/LxMorrowind/LAND records

From Athile

A LAND record starts with:

• INTV
  • int gridX
  • int gridY

when loading an exterior cell, the cell's grid x/y can be used to load up the surrounding LAND landscape data.

Then follows:

• DATA, 6 bytes
• VNML, 12675 bytes (vertex normals)
• VHGT, 4232 bytes (vertex heights)
• WNAM, 81 bytes (???)
• VCLR, 12675 bytes (vertex colors)
• VTEX, 512 bytes (vertex uv coordinates?)

Landscape cells are supposedly 64x64 quads. 64x64 = 4096.

• VNML is 65x65x3 = 12675 in size. THe normals are likely stored as signed bytes that are then normalized by dividing by 128.
• VHGT is 4323 bytes. This could be 65x65 + 7???
• WNAM...what's WNAM?
• VCLR is presumably the same as vertex normals, each byte is 0-255 unsigned byte color value
• VTEX is 8 x 8 x 4 x 2 = 512 bytes. Possibly 2 floats on an 8x8 grid that is interpolated across the grid? Or is it 16 x 16 with a byte per uv?
