Field Documentation

RwReal angularThreshold

angular threshold for vertex welding, in degrees, -1.0f disables the test

RwReal areaThreshold

area threshold for removal of zero area polygons, -1.0f disables the test

RwInt32 convexPartitioningMode

Controls the way polygons are subdivided into triangles. Choose one of RtWingEdgePartitioning

RwInt32 decimationMode

Controls the way edge decimation proceeds, 1 is default, 2 is alternative

RwInt32 decimationPasses

Determines the number of passes through the geometry looking for opportunities to weld polygon pairs

RwInt32 flags

geometry attribute flags

RwReal polyNormalsThreshold

fractional range which polygons normal area have to fall within to be welded, -1.0f disables the test

RwReal polyPreLitsThreshold

fractional range which polygons prelit area have to fall within to be welded, -1.0f disables the test

RwReal polyUVsThreshold

fractional range which polygons uv area have to fall within to be welded, -1.0f disables the test

RwReal preLitThreshold

prelight threshold for vertex welding, -1.0f disables the test

RwBool texelLimits

Specifies if texel based UV limits should be used

RwTextureAddressMode textureMode[rwMAXTEXTURECOORDS]

For each element set to rwTEXTUREADDRESSWRAP, weld vertices according to mod(1) congruent texture coordinates |0-1|0-1|0-1| -> |0-1|1-2|2-3| -> |0 3|

RwReal uvLimitMax

maximum limit for uv coords

RwReal uvLimitMin

minimum limit for uv coords

RwReal uvThreshold

uv threshold for vertex welding, -1.0f disables the test

RwReal weldThreshold

positional threshold for vertex welding, -1.0f disables the test
