Referenced by SupportNode(), and Slic3r::TreeSupport::get_radius().

distance_to_top

int Slic3r::SupportNode::distance_to_top

The number of layers to go to the top of this branch. Negative value means it's a virtual node between support and overhang, which doesn't need to be extruded.

Referenced by SupportNode(), SupportNode(), Slic3r::TreeSupport::insert_dropped_node(), and Slic3r::TreeSupport::plan_layer_heights().

height

is_sharp_tail

bool Slic3r::SupportNode::is_sharp_tail = false

Referenced by SupportNode().

max_move_dist

double Slic3r::SupportNode::max_move_dist = 0.0

mutable

merged_neighbours

std::list<SupportNode*> Slic3r::SupportNode::merged_neighbours

All neighbours (on the same layer) that where merged into this node.

In order to prune branches that can't have any support (because they can't be on the model and the path to the buildplate isn't clear), the entire branch needs to be known.

movement

Point Slic3r::SupportNode::movement

Referenced by Slic3r::TreeSupportData::create_node().

NO_PARENT

SupportNode* Slic3r::SupportNode::NO_PARENT = nullptr

staticconstexpr

obj_layer_nr

int Slic3r::SupportNode::obj_layer_nr

Referenced by SupportNode(), and SupportNode().

overhang

ExPolygon Slic3r::SupportNode::overhang

Referenced by SupportNode().

parent

SupportNode* Slic3r::SupportNode::parent

The originating node for this one, one layer higher.

In order to prune branches that can't have any support (because they can't be on the model and the path to the buildplate isn't clear), the entire branch needs to be known.

Referenced by SupportNode(), SupportNode(), and Slic3r::TreeSupport::smooth_nodes().

parents

std::vector<SupportNode*> Slic3r::SupportNode::parents

Referenced by SupportNode().

position

Point Slic3r::SupportNode::position

The position of this node on the layer.

Referenced by SupportNode(), SupportNode(), Slic3r::TreeSupportData::create_node(), operator==(), and Slic3r::TreeSupport::smooth_nodes().

print_z

coordf_t Slic3r::SupportNode::print_z

radius

double Slic3r::SupportNode::radius = 0.0

mutable

Referenced by SupportNode(), Slic3r::TreeSupport::get_radius(), and Slic3r::TreeSupport::smooth_nodes().

skin_direction

Point Slic3r::SupportNode::skin_direction

The direction of the skin lines above the tip of the branch.

This determines in which direction we should reduce the width of the branch.

Referenced by SupportNode().

support_roof_layers_below

int Slic3r::SupportNode::support_roof_layers_below

The number of support roof layers below this one.

When a contact point is created, it is determined whether the mesh needs to be supported with support roof or not, since that is a per-mesh setting. This is stored in this variable in order to track how far we need to extend that support roof downwards.

Referenced by SupportNode(), SupportNode(), and Slic3r::TreeSupport::insert_dropped_node().

to_buildplate

bool Slic3r::SupportNode::to_buildplate

Whether to try to go towards the build plate.

If the node is inside the collision areas, it has no choice but to go towards the model. If it is not inside the collision areas, it must go towards the build plate to prevent a scar on the surface.

Referenced by SupportNode(), and SupportNode().

type

TreeNodeType Slic3r::SupportNode::type = eCircle

Referenced by SupportNode().

valid

bool Slic3r::SupportNode::valid = true
