Types

type Camera

type Camera struct {
	Type Type

	Pos     gglm.Vec3
	Forward gglm.Vec3
	WorldUp gglm.Vec3

	NearClip float32
	FarClip  float32

	// Perspective data
	Fov         float32
	AspectRatio float32

	// Ortho data
	Left, Right, Top, Bottom float32

	// Matrices
	ViewMat gglm.Mat4

}

func NewOrthographic

func NewOrthographic(pos, forward, worldUp *gglm.Vec3, nearClip, farClip, left, right, top, bottom float32) Camera

func NewPerspective

func NewPerspective(pos, forward, worldUp *gglm.Vec3, nearClip, farClip, fovRadians, aspectRatio float32) Camera

func (*Camera) Update

func (c *Camera) Update()

Update recalculates view matrix and projection matrix. Should be called whenever a camera parameter changes

func (*Camera) UpdateRotation

func (c *Camera) UpdateRotation(pitch, yaw float32)

UpdateRotation calculates a new forward vector and then calls camera.Update()
