SDF for a 2D triangle.

Parameters

• Shape: Which type of triangle to produce. The types are defined by different sets of parameters.
  • Equilateral Triangle: An equilateral triangle (all sides are the same). This is defined based on `Radius`. The triangle is centered around the origin.
  • Isosceles Triangle: An iscosceles triangle (2 sides are the same). This is defined based on `Width` and `Height`. The tip of the triangle is placed at the origin.
  • Inverted Isosceles Triangle:
  • Abritrary Triangle: An arbitrary triangle based on 3 points.
• Radius: The distance from the center to each corner of the triangle. Used for equilateral triangles.
• Height: The distance from the base of an iscosceles triangle to the opposite tip.
• Width: The width of the base of an isosceles triangle.
• Point 1: The first corner position, for an arbitrary triangle.
• Point 2: The second corner position, for an arbitrary triangle.
• Point 3: The third corner position, for an arbitrary triangle.
• Direction:
  • Right (X+):
  • Left (X-):
  • Up (Y+):
  • Down (Y-):
