Function Documentation

◆ atom_positions_colors_and_sizes()

void atom_positions_colors_and_sizes	(	int	style,
		gboolean	to_pick,
		float *	instances )

find atom(s) position(s), color(s) and prepare the data for the OpenGL rendering

Parameters

style	rendering style
to_pick	to pick (1) or to draw (0)
instances	the OpenGL data buffer to fill

Definition at line 625 of file d_atoms.c.

◆ create_atom_lists()

void create_atom_lists ( gboolean to_pick )

prepare atom(s) and clone(s) OpenGL rendering

Parameters

to_pick to pick (1) or to draw (0)

Definition at line 643 of file d_atoms.c.

◆ draw_billboard_quad()

object_3d * draw_billboard_quad ( void )

create a camera-aligned billboard quad proxy for perfect impostors.

The quad has 4 vertices at unit corners (±1, ±1, 0). Each vertex shader for perfect impostors uses the sign of vert.x / vert.y to select the corresponding edge of the tight axis-aligned bounding box in view space.

Draw primitive: GL_TRIANGLE_STRIP with indices [0,1,2,3]. tri 0 → vertices 0,1,2 tri 1 → vertices 1,2,3

Definition at line 273 of file d_atoms.c.

OpenGL 3D sphere object rendering.

Parameters

quality OpenGL quality

Definition at line 198 of file d_atoms.c.
