    • addSpan

      public static void addSpan(Heightfield heightfield, int x, int y, int spanMin, int spanMax, int areaId, int flagMergeThreshold)
      Adds a span to the heightfield. If the new span overlaps existing spans, it will merge the new span with the existing ones. The span addition can be set to favor flags. If the span is merged to another span and the new spanMax is within flagMergeThreshold units from the existing span, the span flags are merged.
      Parameters:
      heightfield - An initialized heightfield.
      x - The width index where the span is to be added. [Limits: 0 <= value < Heightfield::width]
      y - The height index where the span is to be added. [Limits: 0 <= value < Heightfield::height]
      spanMin - The minimum height of the span. [Limit: < spanMax] [Units: vx]
      spanMax - The minimum height of the span. [Limit: <= RecastConstants.SPAN_MAX_HEIGHT] [Units: vx]
      areaId - The area id of the span. [Limit: <= WALKABLE_AREA)
      flagMergeThreshold - The merge theshold. [Limit: >= 0] [Units: vx]

    • rasterizeTriangle

      public static void rasterizeTriangle(Heightfield heightfield, float[] verts, int v0, int v1, int v2, int areaId, int flagMergeThreshold, Telemetry ctx)
      Rasterizes a single triangle into the specified heightfield. Calling this for each triangle in a mesh is less efficient than calling rasterizeTriangles. No spans will be added if the triangle does not overlap the heightfield grid.
      Parameters:
      heightfield - An initialized heightfield.
      verts - An array with vertex coordinates [(x, y, z) * N]
      v0 - Index of triangle vertex 0, will be multiplied by 3 to get vertex coordinates
      v1 - Triangle vertex 1 index
      v2 - Triangle vertex 2 index
      areaId - The area id of the triangle. [Limit: <= WALKABLE_AREA)
      flagMergeThreshold - The distance where the walkable flag is favored over the non-walkable flag. [Limit: >= 0] [Units: vx]

    • rasterizeTriangles

      public static void rasterizeTriangles(Heightfield heightfield, float[] verts, int[] tris, int[] areaIds, int numTris, int flagMergeThreshold, Telemetry ctx)
      Rasterizes an indexed triangle mesh into the specified heightfield. Spans will only be added for triangles that overlap the heightfield grid.
      Parameters:
      heightfield - An initialized heightfield.
      verts - The vertices. [(x, y, z) * N]
      tris - The triangle indices. [(vertA, vertB, vertC) * nt]
      areaIds - The area id's of the triangles. [Limit: <e; WALKABLE_AREA] [Size: numTris]
      numTris - The number of triangles.
      flagMergeThreshold - The distance where the walkable flag is favored over the non-walkable flag. [Limit: >= 0] [Units: vx]

    • rasterizeTriangles

      public static void rasterizeTriangles(Heightfield heightfield, float[] verts, int[] areaIds, int numTris, int flagMergeThreshold, Telemetry ctx)
      Rasterizes a triangle list into the specified heightfield. Expects each triangle to be specified as three sequential vertices of 3 floats. Spans will only be added for triangles that overlap the heightfield grid.
      Parameters:
      heightfield - An initialized heightfield.
      verts - The vertices. [(x, y, z) * numVerts]
      areaIds - The area id's of the triangles. [Limit: <= WALKABLE_AREA] [Size: numTris]
      numTris - The number of triangles.
      flagMergeThreshold - The distance where the walkable flag is favored over the non-walkable flag. [Limit: >= 0] [Units: vx]
