func CalculateCenter(v []Vertex) [2]float32

func CreateVertexBuffer(device *wgpu.Device, vertices []Vertex, width float32, height float32) *wgpu.Buffer

func ScreenToNDC(x, y, screenWidth, screenHeight float32) [3]float32

ScreenToNDC transforms screen space coordinates to NDC. screenWidth and screenHeight are the dimensions of the screen.

}

Vertex represents a single vertex in the shape.

func ConvertVerticesToNDC(vertices []Vertex, screenWidth, screenHeight float32) []Vertex

convertVerticesToNDC converts an array of vertices from screen space to NDC.
