Member Function Documentation

◆ createRenderer()

score::gfx::NodeRenderer * score::gfx::ISFNode::createRenderer ( RenderList &  r) const
overridevirtualnoexcept

Create a renderer in a given context for this node.

Implements score::gfx::Node.

◆ process() [1/9]

virtual void score::gfx::ProcessNode::process ( int32_t  port,
const FunctionMessage &   
)
virtual

Reimplemented from score::gfx::ProcessNode.

◆ process() [2/9]

void score::gfx::ProcessNode::process ( int32_t  port,
const ossia::audio_vector &  v 
)
virtual

Reimplemented from score::gfx::ProcessNode.

◆ process() [3/9]

void score::gfx::ProcessNode::process ( int32_t  port,
const ossia::buffer_spec &  func 
)
virtual

Reimplemented from score::gfx::ProcessNode.

◆ process() [4/9]

void score::gfx::ProcessNode::process ( int32_t  port,
const ossia::transform3d &  v 
)
virtual

Reimplemented from score::gfx::ProcessNode.

◆ process() [5/9]

void score::gfx::ProcessNode::process ( int32_t  port,
const ossia::value &  v 
)
virtual

Take what the list supplies and leave the rest of the uniform alone.

ossia::convert<vec4f>(list) starts from a zeroed vector and fills the components the list has, so three floats arriving at a four-component uniform wrote a zero into the fourth. On a colour that is alpha, and the shape went black: an OSC address carrying rgb, or anything else that sends a colour without its alpha. A cable did not show it because it carries all four.

Leaving the missing components untouched is also the right answer for a non-colour uniform: a partial update should not silently zero what it did not mention.

Reimplemented from score::gfx::ProcessNode.

◆ process() [6/9]

void score::gfx::ISFNode::process ( int32_t  port,
const ossia::value &  v 
)
overridevirtual

An event input fires for one frame on true – and on an impulse, which the generic port writer ignores: a cable or a message could not fire it.

Reimplemented from score::gfx::ProcessNode.

◆ process() [7/9]

void score::gfx::ISFNode::process ( Message &&  msg)
overridevirtual

Process a message from the execution engine.

Reimplemented from score::gfx::Node.

◆ process() [8/9]

void score::gfx::ProcessNode::process ( Message &&  msg)
overridevirtual

Process a message from the execution engine.

Reimplemented from score::gfx::Node.

◆ process() [9/9]

void score::gfx::ProcessNode::process ( Timings  tk)
virtual

Reimplemented from score::gfx::ProcessNode.
