|
pure virtual |
convenience method to visualize a camera position
name | entity name |
K | intrinsic matrix |
imsize | image size |
zFar | far plane in camera coordinates |
tvec | translation |
rot | Rodrigues vector or 3x3 rotation matrix |
color | line color |
|
pure virtual |
place an entity of a mesh in the scene
the mesh needs to be created beforehand. Either programmatically by e.g. createPointCloudMesh or by placing the respective file in a resource location.
name | entity name |
meshname | mesh name |
tvec | translation |
rot | Rodrigues vector or 3x3 rotation matrix |
|
pure virtual |
creates a point light in the scene
name | entity name |
tvec | translation |
rot | Rodrigues vector or 3x3 rotation matrix |
diffuseColor | |
specularColor |
|
pure virtual |
convenience method to force the "up" axis to stay fixed
works with both programmatic changes and SCENE_INTERACTIVE
useFixed | whether to enforce the fixed yaw axis |
up | the axis to be fixed |
|
pure virtual |
Retrieves the current camera pose
R | 3x3 rotation matrix |
tvec | translation vector |
invert | return the inverted pose |
|
pure virtual |
read back the texture of an active compositor
compname | name of the compositor |
texname | name of the texture inside the compositor |
mrtIndex | if texture is a MRT, specifies the attachment |
out | the texture contents |
|
pure virtual |
get the depth for the current frame.
return the per pixel distance to the camera in world units
|
pure virtual |
get a list of available entity animations
name | entity name |
out | the animation names |
|
pure virtual |
Retrieves the current pose of an entity
name | entity name |
R | 3x3 rotation matrix |
tvec | translation vector |
invert | return the inverted pose |
|
pure virtual |
get the property of an entity
name | entity name |
prop | EntityProperty |
value | the value |
|
pure virtual |
read back the image generated by the last call to waitKey
|

|
pure virtual |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
|
pure virtual |
|
pure virtual |
convenience method to orient the camera to a specific entity
target | entity name |
offset | offset from entity centre |
|
pure virtual |
Sets the current camera pose
tvec | translation |
rot | Rodrigues vector or 3x3 rotation matrix |
invert | use the inverse of the given pose |
|
pure virtual |
enable an ordered chain of full-screen post processing effects
this way you can add distortion or SSAO effects. The effects themselves must be defined inside Ogre .compositor scripts.
names | compositor names that will be applied in order of appearance |
|
pure virtual |
convenience method to orient an entity to a specific entity. If target is an empty string the entity looks at the given offset point
origin | entity to make look at |
target | name of target entity |
offset | offset from entity centre |
|
pure virtual |
set entity pose in the world coordinate space.
name | enitity name |
tvec | translation |

value | the value |
subEntityIdx | index of the sub-entity (default: all) |
|
