getModelMatrix()

glm::mat4 solarsim::TransformComponent::getModelMatrix ( ) const

inline

Computes the model transformation matrix.

Returns

glm::mat4 The composed model matrix (translation * rotation * scale)

Note

Only recalculates when dirty flag is set

Warning

Modifying position, rotation, or scale does NOT currently set dirty=true automatically

Field Documentation

dirty

bool solarsim::TransformComponent::dirty = true

mutable

Flag indication if matrix needs recalculation

modelMatrix

glm::mat4 solarsim::TransformComponent::modelMatrix

mutable

Cached tranformation matrix (set via getModelMatrix below)

position

glm::vec3 solarsim::TransformComponent::position {0.0f}

World space position vector

rotation

glm::quat solarsim::TransformComponent::rotation {1.0f, 0.0f, 0.0f, 0.0f}

Orientation as a quaternion

scale

glm::vec3 solarsim::TransformComponent::scale {1.0f}

Scaling factors
