DESCRIPTION

The hwDisc class creates a circular disc of a given radius about the origin. The disc lies in the XY plane, and its front surface faces positive Z. The default texture coordinates for a disc are as if the disc were cut out of the (square) texture map projected on the XY plane with the center at the origin.

C EXAMPLE

    /* Draw a purple twosided disc of radius 2.0 */
    hwObject
        disc;

    disc = hwDisc->create( hwDisc );
    HW_MODIFY_1B( disc, hwStrTwoSided, HW_TRUE );
    HW_MODIFY_1F( disc, hwStrRadius, 2.0 );
    HW_MODIFY_3F( disc, hwStrColor, 1.0, 0.0, 1.0 );
    disc->draw( disc );
    disc->destroy( disc );

OBJECT FILE EXAMPLE

    # A purple twosided disc of radius 2.0
    hwDisc disc {
        TwoSided = True
        Radius = 2.0
        Color = {1,0,1}
    }
