RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Overloaded version of triangleRasterize() with color-only rendering

triangleRasterizeColor(vertices: Mat, indices: Mat, colors: Mat, colorBuf: Mat, world2cam: Mat, fovY: number, zNear: number, zFar: number, settings: TriangleRasterizeSettings): void;

2 available overloads

triangleRasterizeColor(vertices: Mat, indices: Mat, colors: Mat, colorBuf: Mat, world2cam: Mat, fovY: number, zNear: number, zFar: number): void;

triangleRasterizeColor(vertices: Mat, indices: Mat, colors: Mat, colorBuf: Mat, world2cam: Mat, fovY: number, zNear: number, zFar: number, settings: TriangleRasterizeSettings): void;

vertices

vertices coordinates array. Should contain values of CV_32FC3 type or a compatible one (e.g. cv::Vec3f, etc.)

indices

triangle vertices index array, 3 per triangle. Each index indicates a vertex in a vertices array. Should contain CV_32SC3 values or compatible

colors

per-vertex colors of CV_32FC3 type or compatible. Can be empty or the same size as vertices array. If the values are out of [0; 1] range, the result correctness is not guaranteed

colorBuf

Input/output value, modified by the native operation. an array representing the final rendered image. Should containt CV_32FC3 values and be the same size as depthBuf. Not cleared before rendering, i.e. the content is reused as there is some pre-rendered scene.

world2cam

a 4x3 or 4x4 float or double matrix containing inverted (sic!) camera pose

fovY

field of view in vertical direction, given in radians

zNear

minimum Z value to render, everything closer is clipped

zFar

maximum Z value to render, everything farther is clipped

settings

see TriangleRasterizeSettings. By default the smooth shading is on, with CW culling and with disabled GL compatibility
