Enums¶

Enumerations¶
Enum	Description
`RaeptorCogs::CameraFlags`	Camera flags enumeration.

enum class RaeptorCogs::CameraFlags : uint32_t ¶

Camera flags enumeration.

Defines flags for camera state management.

Values:

enumerator NONE¶: No flags set.

enumerator NEEDS_REBUILD_VIEW_MATRIX¶: Indicates the view matrix needs to be rebuilt.

enumerator NEEDS_REBUILD_PROJECTION_MATRIX¶: Indicates the projection matrix needs to be rebuilt.

Classes¶

Classes¶
Class	Description
`RaeptorCogs::Camera`	Base Camera class.
`RaeptorCogs::Camera2D`	2D Camera class.

class Camera¶

Base Camera class.

Provides an interface for 2D and 3D camera implementations.

Subclassed by RaeptorCogs::Camera2D

Public Functions

virtual ~Camera() = default¶: Virtual destructor for Camera.

virtual glm::mat4 getViewMatrix() = 0¶: Get the view matrix of the camera.

virtual glm::mat4 getProjectionMatrix() = 0¶: Get the projection matrix of the camera.

Protected Attributes

glm::mat4 viewMatrix = glm::mat4(1.0f)¶: View matrix of the camera.

glm::mat4 projectionMatrix = glm::mat4(1.0f)¶: Projection matrix of the camera.

CameraFlags flags = CameraFlags::NEEDS_REBUILD_VIEW_MATRIX | CameraFlags::NEEDS_REBUILD_PROJECTION_MATRIX ¶: Flags indicating the state of the camera.

class Camera2D : public RaeptorCogs::Camera, public RaeptorCogs::Component2D ¶

2D Camera class.

Implements a simple 2D camera with position and zoom.

Public Functions

Camera2D()¶: Constructor for Camera2D.

~Camera2D()¶: Destructor for Camera2D.

virtual glm::mat4 getViewMatrix() override¶: Get the view matrix of the camera.

virtual glm::mat4 getProjectionMatrix() override¶: Get the projection matrix of the camera.

void setPosition(const glm::vec2 &pos)¶: Set the position of the camera.

void setZoom(float z)¶: Set the zoom level of the camera.

float getPositionX() const¶: Get the X position of the camera.

float getPositionY() const¶: Get the Y position of the camera.

glm::vec2 getPosition() const¶: Get the position of the camera as a vector.

float getZoom() const¶: Get the zoom level of the camera.

virtual void update(GAPI::Common::RenderPipeline &pipeline) override¶: Update the camera component.

Private Functions

void rebuildViewMatrix()¶: Rebuild the view matrix based on position and zoom.

void rebuildProjectionMatrix()¶: Rebuild the projection matrix based on zoom.

Private Members

glm::vec2 position = glm::vec2(0.0f, 0.0f)¶: Position of the camera in 2D space.

float zoom = 1.0f¶: Zoom level of the camera.
