Types

type Axes

type Axes struct {
	graphic.Lines
}

Axes is a visual representation of the three axes.

func NewAxes

func NewAxes(size float32) *Axes

NewAxes returns a pointer to a new Axes object.

type Grid

type Grid struct {
	graphic.Lines
}

Grid is a visual representation of a grid.

func NewGrid

func NewGrid(size, step float32, color *math32.Color) *Grid

NewGrid creates and returns a pointer to a new grid helper with the specified size and step.

type Normals

type Normals struct {
	graphic.Lines
	// contains filtered or unexported fields
}

Normals is the visual representation of the normals of a target object.

func NewNormals

func NewNormals(ig graphic.IGraphic, size float32, color *math32.Color, lineWidth float32) *Normals

NewNormals creates a normals helper for the specified IGraphic, with the specified size, color, and lineWidth.

func (*Normals) Update

func (nh *Normals) Update()

Update should be called in the render loop to update the normals based on the target object.
