Methods
staticSolidQuad
static void SolidQuad(const Area2 &area, const SPtr<MeshData> &meshData, u32 vertexOffset, u32 indexOffset)
Fills the mesh data with vertices representing a quad (2 triangles).
- area
- Area in which to draw the quad.
- meshData
- Mesh data that will be populated.
- vertexOffset
- Offset in number of vertices from the start of the buffer to start writing at.
- indexOffset
- Offset in number of indices from the start of the buffer to start writing at.
staticPixelLine
static void PixelLine(const Vector2 &a, const Vector2 &b, const SPtr<MeshData> &meshData, u32 vertexOffset, u32 indexOffset)
Fills the mesh data with vertices representing a per-pixel line.
- a
- Start point of the line.
- b
- End point of the line.
- meshData
- Mesh data that will be populated.
- vertexOffset
- Offset in number of vertices from the start of the buffer to start writing at.
- indexOffset
- Offset in number of indices from the start of the buffer to start writing at.
staticQuadLine
static void QuadLine(const Vector2 &a, const Vector2 &b, float width, float border, const Color &color, const SPtr<MeshData> &meshData, u32 vertexOffset, u32 indexOffset)
Fills the mesh data with vertices representing a line of specific width as a quad.
- a
- Start point of the line.
- b
- End point of the line.
- width
- Width of the line.
- border
- Optional border that will increase the width and the length at both end-points. Useful if you are using some kind of filtering for the line rendering, as the filtered pixels can belong to the border region.
- color
- Color of the line.
- meshData
- Mesh data that will be populated by this method.
- vertexOffset
- Offset in number of vertices from the start of the buffer to start writing at.
- indexOffset
- Offset in number of indices from the start of the buffer to start writing at.
staticPixelLineList
static void PixelLineList(const Vector<Vector2> &linePoints, const SPtr<MeshData> &meshData, u32 vertexOffset, u32 indexOffset)
Fills the mesh data with vertices representing per-pixel lines.
- linePoints
- A list of start and end points for the lines. Must be a multiple of 2.
- meshData
- Mesh data that will be populated.
- vertexOffset
- Offset in number of vertices from the start of the buffer to start writing at.
- indexOffset
- Offset in number of indices from the start of the buffer to start writing at.
staticQuadLineList
static void QuadLineList(const Vector<Vector2> &linePoints, float width, float border, const Color &color, const SPtr<MeshData> &meshData, u32 vertexOffset, u32 indexOffset)
Fills the mesh data with vertices representing a polyline of specific width as a set of quads.
- linePoints
- A list of start and end points for the lines.
- width
- Width of the line.
- border
- Optional border that will increase the width and the length at both end-points. Useful if you are using some kind of filtering for the line rendering, as the filtered pixels can belong to the border region.
- color
- Color of the line.
- meshData
- Mesh data that will be populated by this method.
- vertexOffset
- Offset in number of vertices from the start of the buffer to start writing at.
- indexOffset
- Offset in number of indices from the start of the buffer to start writing at.
staticQuadLineList
static void QuadLineList(const Vector2 *linePoints, u32 numPoints, float width, float border, u8 *outVertices, u32 vertexStride, bool indexed)
Fills the provided buffers with vertices representing a polyline of specific width as a set of quads (triangle list).
- linePoints
- A list of start and end points for the lines.
- numPoints
- Number of points in the buffer.
- width
- Width of the line.
- border
- Optional border that will increase the width and the length at both end-points. Useful if you are using some kind of filtering for the line rendering, as the filtered pixels can belong to the border region.
- outVertices
- Pre-allocated buffer for the vertices, of size ((numLines * 2) + 2) * if is true, or (numLines * 6) * if false.
- vertexStride
- Distance between two vertices in the output buffer. Must be at least sizeof(Vector2).
- indexed
- If true there will be ((numLines * 2) + 2) vertices generated, assuming an index buffer will be used for rendering. If false then (numLines * 6) vertices will be generated.
