Static extension with additional helpers for ceramic.Mesh
Static methods
staticcreateQuad(mesh:Mesh, width:Float, height:Float, floatsPerVertex:Int = -1):Void
Generate vertices, indices and uvs on the given mesh to make it form a quad
Parameters:
mesh | The mesh to work with |
|---|---|
width | With of the quad to form |
height | Height of the quad to form |
floatsPerVertex | (optional) Number of floats per vertex
Set to 2 for regular quad, 6 for quads with dark color, must be 2 or higher.
If not provided, will resolve the value from |
staticsetDarkColor(mesh:Mesh, darkColor:Color):Void
Assign a dark color to the given mesh. The mesh is expected to have 6 floats per vertex and 4 last vertices will be used for color values.
Parameters:
mesh | The mesh to work with |
|---|---|
darkColor | The dark color to assign |
staticsetDarkAlphaColor(mesh:Mesh, darkAlphaColor:AlphaColor):Void
Assign a dark color (with alpha included) to the given mesh. The mesh is expected to have 6 floats per vertex and 4 last vertices will be used for color values.
Parameters:
mesh | The mesh to work with |
|---|---|
darkColor | The dark color to assign |
staticcreateArc(mesh:Mesh, radius:Float, angle:Float, thickness:Float, sides:Int, borderPosition:BorderPosition):Void
Generate vertices and indices to draw arc, pie, ring or disc geometry
Parameters:
mesh | The mesh to work with |
|---|---|
radius | Radius of the arc |
angle | Angle (from 0 to 360). 360 will make it draw a full circle/ring |
thickness | Thickness of the arc. If same value as radius and borderPosition is |
sides | Number of sides. Higher is smoother but needs more vertices |
borderPosition | Position of the drawn border |
staticcreateVerticesGrid(mesh:Mesh, columns:Int, rows:Int, width:Float, height:Float, staggerX:Float = 0, staggerY:Float = 0, attrLength:Int = 0, ?attrValues:Array<Float>):Void
Create vertices to form a grid with the given options
Parameters:
mesh | The mesh to work with |
|---|---|
columns | The number of columns in the grid |
rows | The number of rows in the grid |
width | The total width of the grid |
height | The total height of the grid |
staggerX | (optional, default 0) A stagger value to offset rows by this value |
staggerY | (optional, default 0) A stagger value to offset columns by this value |
attrLength | (optional, default 0) The number of attribute values per vertex |
attrValues | (optional) The attributes buffer that will be added to vertex data |
staticcreateIndicesGrid(mesh:Mesh, columns:Int, rows:Int, mirrorX:Bool = false, mirrorY:Bool = false, mirrorFlip:Bool = false):Void
Create indices to form a grid with the given options
Parameters:
mesh | The mesh to work with |
|---|---|
columns | The number of columns in the grid |
rows | The number of rows in the grid |
mirrorX | (optional, default false) Mirror triangles horizontally in odd columns |
mirrorY | (optional, default false) Mirror triangles vertically in odd rows |
mirrorFlip | (optional, default false) Invert the mirroring described by |
staticcreateUVsGrid(mesh:Mesh, columns:Int, rows:Int):Void
Create uvs to match a grid with the given options. The uvs will be distributed linearly across the mesh so that when displaying a texture it would be stretched to the grid.
Parameters:
mesh | The mesh to work with |
|---|---|
columns | The number of columns in the grid |
rows | The number of rows in the grid |
