QCameraLens

PyQt5.Qt3DRender.QCameraLens

Inherits from QComponent.

Description

QCameraLens specifies the projection matrix that will be used to define a Camera for a 3D scene.

Enums

ProjectionType

Specifies which parameters of QCameraLens are used to compute the projection matrix.

Member	Value	Description
CustomProjection	3	Custom user-defined projection
FrustumProjection	2	Frustum projection
OrthographicProjection	0	Orthogonal projection
PerspectiveProjection	1	Perspective projection

Methods

__init__(parent: QNode = None)

setExposure().

---

farPlane() → float

See also

setFarPlane().

---

fieldOfView() → float

See also

setFieldOfView().

---

left() → float

See also

setLeft().

---

nearPlane() → float

See also

setNearPlane().

---

projectionMatrix() → QMatrix4x4

See also

setProjectionMatrix().

---

projectionType() → ProjectionType

See also

setProjectionType().

---

right() → float

See also

setRight().

---

setAspectRatio(float)

Sets the projection’s aspect ratio to aspectRatio. This triggers a projection matrix update.

Note: this has no effect if the projection type is not PerspectiveProjection.

See also

aspectRatio().

---

setBottom(float)

Sets the projection’s bottom window coordinate to bottom. This triggers a projection matrix update.

Note: this has no effect if the projection type is PerspectiveProjection.

See also

bottom().

---

setExposure(float)

Sets the camera lens’ exposure

See also

exposure().

---

setFarPlane(float)

Sets the projection’s far plane to farPlane. This triggers a projection matrix update.

See also

farPlane().

---

setFieldOfView(float)

Sets the projection’s field of view to fieldOfView degrees. This triggers a projection matrix update.

Note: this has no effect if the projection type is not PerspectiveProjection.

See also

fieldOfView().

---

setFrustumProjection(float, float, float, float, float, float)

Defines an orthographic projection based on left, right, bottom, top, nearPlane, farPlane.

---

setLeft(float)

Sets the projection’s lower left window coordinate to left. This triggers a projection matrix update.

Note: this has no effect if the projection type is PerspectiveProjection.

See also

left().

---

setNearPlane(float)

Sets the projection’s near plane to nearPlane. This triggers a projection matrix update.

See also

nearPlane().

---

setOrthographicProjection(float, float, float, float, float, float)

Defines an orthographic projection based on left, right, bottom, top, nearPlane, farPlane.

---

setPerspectiveProjection(float, float, float, float)

Defines a perspective projection based on fieldOfView, aspectRatio, nearPlane, farPlane.

---

setProjectionMatrix(QMatrix4x4)

Sets the project matrix to projectionMatrix.

Note: This will set the projection type to CustomProjection and thus ignore all other camera parameters that might have been specified.

See also

projectionMatrix().

---

setProjectionType(ProjectionType)

Sets the lens’ projection type projectionType.

Note: Qt3DRender::QCameraLens::Frustum and PerspectiveProjection are two different ways of specifying the same projection.

See also

projectionType().

---

setRight(float)

Sets the projection’s upper right window coordinate to right. This triggers a projection matrix update.

Note: this has no effect if the projection type is PerspectiveProjection.

See also

right().

---

setTop(float)

Sets the projection’s top window coordinate to top. This triggers a projection matrix update.

Note: this has no effect if the projection type is PerspectiveProjection.

See also

top().

---

top() → float

setTop().
