Types ¶
type FPS ¶
type FPS struct {
Pos mgl32.Vec3
Target mgl32.Vec3
Up mgl32.Vec3
Right mgl32.Vec3
Fov float32
Near float32
Far float32
// contains filtered or unexported fields
}
FPS moves in the view direction while the viewing direction can be changed.
func Make ¶
Make creates a FPS with the viewport of width and height and a radius from the origin. It assumes a field of view of 45 degrees and a near and far plane at 0.1 and 100.0 respectively.
func MakeDefault ¶
MakeDefault creates a FPS camera with the viewport of width and height and a position. It assumes a field of view of 45 degrees and a near and far plane at 0.1 and 100.0 respectively.
func New ¶
New creates a reference to a FPS with the viewport of width and height and a radius from the origin. It assumes a field of view of 45 degrees and a near and far plane at 0.1 and 100.0 respectively.
func NewDefault ¶
NewDefault creates a reference to a FPS camera with the viewport of width and height and a position. It assumes a field of view of 45 degrees and a near and far plane at 0.1 and 100.0 respectively.
func (*FPS) GetPerspective ¶
GetPerspective returns the perspective projection of the camera.
func (*FPS) GetViewPerspective ¶
GetViewPerspective returns P*V.
func (*FPS) OnCursorPosMove ¶
OnCursorPosMove is a callback handler that is called every time the cursor moves.
func (*FPS) OnKeyPress ¶
OnKeyPress is a callback handler that is called every time a keyboard key is pressed.
func (*FPS) OnMouseButtonPress ¶
OnMouseButtonPress is a callback handler that is called every time a mouse button is pressed or released.
func (*FPS) OnMouseScroll ¶
OnMouseScroll is a callback handler that is called every time the mouse wheel moves.
func (*FPS) Rotate ¶
Rotate adds delta angles in degrees to the theta and phi angles. Where theta is the vertical angle and phi the horizontal angle.
func (*FPS) SetPos ¶
SetPos updates the target point of the camera. It requires to call Update to take effect.
