|
<p>This threshold is used by the collision detection to determine if a height field edge is convex and can generate contact points. Usually the convexity of an edge is determined from the angle (or cosine of the angle) between the normals of the faces sharing that edge. The height field allows a more efficient approach by comparing height values of neighboring vertices. This parameter offsets the comparison. Smaller changes than 0.5 will not alter the set of convex edges. The rule of thumb is that larger values will result in fewer edge contacts.</p>
|
|
<p>This parameter is ignored in contact generation with sphere and capsule primitives.</p>

<p>There are nbRows * nbColumn samples in the array, which define nbRows * nbColumn vertices and cells, of which (nbRows - 1) * (nbColumns - 1) cells are actually used.</p>

<p>The array index of sample(row, column) = row * nbColumns + column. The byte offset of sample(row, column) = sampleStride * (row * nbColumns + column). The sample data follows at the offset and spans the number of bytes defined by the format. Then there are zero or more unused bytes depending on sampleStride before the next sample.</p>
