List of formats, and how to read them
Id | Type | |

0x00 | Float | uncompressed float |
0x01 | Float2 | 2 uncompressed floats |
0x02 | Float3 | 3 uncompressed floats |
0x03 | Float4 | 4 uncompressed floats |
0x04 | UByte4 | 4 uncompressed bytes |
0x05 | ColorUByte4 | 3 floats in 4 bytes. Order is little-endian, use the low order byte (4th) as an unsigned scaler value. For each remaining signed byte, if negative, add it, if positive, subtract it, then multiple the result by 1/scaler, or by 1/127 if scaler is 0
This entry needs explaining more clearly. In Little-endian, the low order byte is first, not fourth. The statements "add it" and "subtract it" do not explain what "it" is. Here and subsequently: "multiply by 1/xxx" - why not just "divide by xxx"? Pljones 23:07, 17 January 2011 (UTC) |
0x06 | Short2 | 2 floats in two words. Multiply the signed values by 1/32767 |
0x07 | Short4 | 3 floats in 4 words. The fourth word is an unsigned scaler, multiply each signed word by 1/scaler (or use 65535 if zero) |
0x08 | UByte4N | |
0x09 | Short2N | |
0x0A | Short4N | |
0x0B | UShort2N | |
