Luna::VG::COMMAND_CIRCLE_Q1

constexpr f32 COMMAND_CIRCLE_Q1 = 4.0f

The command code that draws one circle part in the first quadrant.

This command takes 4 points: {COMMAND_CIRCLE_Q1, R, BEGIN, END}* R: The radius of the circle.

• BEGIN: The beginning angle of the circle part in degrees. The value should be in [0, 90].

• END: The ending angle of the circle part in degrees. The value should be in [0, 90].

All circle drawing commands take three data points:

• R: The radius of the circle.

• BEGIN: The beginning angle of the circle in degrees.

• END: The end angle of the circle in degrees. If the end angle is greater than the beginning angle, the circle is drawn counter-clockwisly, otherwise, the circle is drawn clockwisly.
