TS3DTK_VERTEX_LIT

A vertex with color information without texture coordinates.

Declaration:

TS3DTK_VERTEX_LIT = record
  X: TS3DTKVALUE;
  Y: TS3DTKVALUE;
  Z: TS3DTKVALUE;
  W: TS3DTKVALUE;
  B: BYTE;
  G: BYTE;
  R: BYTE;
  A: BYTE;
end;

Fields:

• X - X coordinate in screen space (pixels). Remember that TS3DTKVALUE is a floating point type - vertices can lie "between" pixels. This must be a value between 0 to 4095, inclusive.
• Y - Y coordinate in screen space. Similar to X. Also must be between 0 to 4095.
• Z - Z value to use for z buffering. Only 16bit zbuffers are supported so this must be a value between 0 to 65535.
• W - Ignored.
• B - Blue component for the color.
• G - Green component for the color.
• R - Red component for the color.
• A - Alpha component for the color, used for alpha blending and fog density.

Description:

This record is used to draw triangles without any texture applied to them (ie. gouraud shading). The W field is ignored and only exists so that the same vertex data can be used for both textured and untextured rendering.

Unit: S3DTK
