~CurveGeometry() override#
-
virtual void render(const Camera &camera) override#
Render the cylinder geometry.
- Parameters:
camera – The current camera to be used for rendering.
-
void addPoint(const Vector3f &pos, const Vector3ub &color, float radius, size_t group, size_t id)#
-
inline const std::vector<Line*> &lines() const#
-
void tessellate(size_t lineIndex, std::vector<ColorNormalVertex> &vertices, std::vector<unsigned int> &indices) const#
Compute the triangle mesh (or, for flat lines, the centre-line polyline) for one line, without touching OpenGL. This is exactly the data uploaded to the GPU by render(), and honours the circleResolution(), appendCirclePoints() and computeScale() hooks of subclasses.
- Parameters:
lineIndex – Index into lines().
vertices – Output vertices (cleared first). Empty if the line is too short to produce any geometry (or lineIndex is out of range).
indices – Output triangle list into
vertices(cleared first). Empty for flat lines, see isFlatLine().
-
bool isFlatLine(size_t lineIndex) const#
- Returns:
true if the line is drawn on screen as a GL_LINE_STRIP of width -lines()[lineIndex]->radius pixels. For such lines tessellate() returns the polyline vertices along the curve (colour and a normal each) and no indices.
