Public Methods

Camera()

virtual ~Camera()

void setFieldOfView(double fovy, double aspectRatio)

Set field of view and window aspect ratio.

void setFieldOfViewY(double fovy)

double getFieldOfViewY() const

void setAspectRatio(double aspectRatio)

double getAspectRatio() const

void home()

hardwired home view for now, looking straight down the Z axis at the origin, with 'up' being the y axis

void setView(Vec3 eyePoint, Vec3 lookPoint, Vec3 upVector)

Set the View, the up vector should be orthogonal to the look vector

const Vec3& getEyePoint() const

get the eyepoint.

const Vec3& getLookPoint() const

get the lookpoint.

const Vec3& getUpVector() const

which way is up?

Vec3 getSideVector() const

calculate side vector

Vec3 getLookVector() const

calculate look vector

float getFocalDistance() const

calculate focal distance

void setNearPlane(double nearPlane)

set the near plane.

double getNearPlane() const

get the near plane.

void setFarPlane(double farPlane)

set the far plane.

double getFarPlane() const

get the far plane.

void draw_PROJECTION() const

Set up the OpenGL GL_PROJECTION matrix.

void draw_MODELVIEW() const

Set up the OpenGL GL_MODELVIEW matrix.

void mult(const Camera& camera, const Matrix& m)

post multiply a camera by matrix

void mult(const Matrix& m, const Camera& camera)

pre multiply a camera by matrix

void setFieldOfView(double fovy, double aspectRatio)

Set field of view and window aspect ratio. The parameters have the same meaning as their counterparts in gluPerspective(fovy,aspectRatio

void setFieldOfViewY(double fovy)

double getFieldOfViewY() const

void setAspectRatio(double aspectRatio)

double getAspectRatio() const

void home()

hardwired home view for now, looking straight down the Z axis at the origin, with 'up' being the y axis

void setView(Vec3 eyePoint, Vec3 lookPoint, Vec3 upVector)

Set the View, the up vector should be orthogonal to the look vector

const Vec3& getEyePoint() const

const Vec3& getLookPoint() const

get the lookpoint.

const Vec3& getUpVector() const

void setNearPlane(double nearPlane)

set the near plane.

double getNearPlane() const

get the near plane.

void setFarPlane(double farPlane)

set the far plane.

double getFarPlane() const

get the far plane.

void draw_PROJECTION() const

Set up the OpenGL GL_PROJECTION matrix. Enters the GL_PROJECTION mode, sets up matrix, then resets model GL_MODELVIEW, which is by OpenGL convention the default.

void draw_MODELVIEW() const

Set up the OpenGL GL_MODELVIEW matrix. Enters the GL_MODELVIEW mode, sets matrix to identity and then sets matrix up according to camera, eye point, center point and upvector.

void mult(const Camera& camera, const Matrix& m)

post multiply a camera by matrix

void mult(const Matrix& m, const Camera& camera)

pre multiply a camera by matrix
