MeshUtilsGenerateCylindricalTextureCoordinates(Vector3, Int32, Vector3, NullableVector2, NullableVector2, Vector3, Vector3, Boolean) Method |
Generate texture coordinates for the given vertices and triangleIndices.
Texture coordinates are computed using cylindrical projection.
Texture coordinates for positions that are parallel to the cylinderDirectionVector use simple planar projection.
Texture coordinates for other positions are computed based on the angle from the cylinder center axis to the position.

Syntax public static Vector2[] GenerateCylindricalTextureCoordinates(
Vector3[] positions,
int[] triangleIndices,
Vector3[]? normals,
Vector2? planeBoundsMin,
Vector2? planeBoundsMax,
Vector3 cylinderDirectionVector,
Vector3 cylinderPlaneHeightVector,
bool invertBottomYCoordinate = true
)
Parameters
- positions Vector3
- Array of 3D vertex positions that define the mesh.
- triangleIndices Int32
- Array of triangle indices that define the mesh.
- normals Vector3
- Array of 3D normals that define the mesh. If normals are not provided (null), they are computed from positions and indices.
- planeBoundsMin NullableVector2
- Optional minimum point of the 2D bounding box that defines the bounds of the cylinders top and bottom plane.
- planeBoundsMax NullableVector2
- Optional maximum point of the 2D bounding box that defines the bounds of the cylinders top and bottom plane.
- cylinderDirectionVector Vector3
- Direction vector of the cylinder (its upright / 3D height direction).
- cylinderPlaneHeightVector Vector3
- Direction vector along the cylinder's top and bottom planes (the 2D height direction of the 2D circle plane).
- invertBottomYCoordinate Boolean (Optional)
- Invert the bottom Y texture coordinate, for example to make the text on the bottom texture correctly oriented.
Return Value
Vector2Array of generated texture coordinates.
