Detailed Description
Options for generating a rounded plane mesh.
Member Function Documentation
◆ project_to_valid_range()
|
inline |
Clamps all parameters to valid ranges.
This method ensures that:
- width and height are non-negative
- bevel_radius is non-negative and at most half the minimum of width and height
- width_segments and height_segments are at least 1
- bevel_segments is at least 1 when bevel_radius > epsilon, or 0 otherwise
Member Data Documentation
◆ width
| Scalar width = 1 |
Width of the plane along the X-axis.
Must be non-negative.
◆ height
| Scalar height = 1 |
Height of the plane along the Z-axis.
Must be non-negative.
◆ bevel_radius
| Scalar bevel_radius = 0 |
Radius of the bevel/rounding applied to the plane corners.
A value of 0 creates sharp corners. The bevel radius is automatically clamped to at most half the minimum of width and height.
◆ width_segments
| Index width_segments = 1 |
Number of subdivisions along the width (X-axis).
Must be at least 1.
◆ height_segments
| Index height_segments = 1 |
Number of subdivisions along the height (Z-axis).
Must be at least 1.
◆ bevel_segments
| Index bevel_segments = 8 |
Number of subdivisions for the bevel/rounded corners.
Higher values create smoother rounded corners. This parameter is ignored if bevel_radius is 0 or smaller than epsilon. Must be at least 1 when bevel_radius > epsilon.
