WebWith antialiasing enabled, non-integer line widths are possible, and pixels on the boundaries are typically drawn at less than full intensity.

WebJun 23, 2009 · 3.0: no wide lines, regular lines are there. VBOs and GL_LINES 3.1: wide lines are back. Lines get antialiased if you render to a MSAA/CSAA framebuffer. I don’t know if antialiasing tricks on non-MSAA buffer via hints is supported. WebThen we redraw discontinuity edges (such as silhouettes and material boundaries) as antialiased lines. For example, Figure 22-8a shows a single triangle drawn without antialiasing. Figure 22-8b shows its edges drawn as prefiltered antialiased lines. By drawing these lines on top of the original geometry, we obtain the result in Figure 22-8c. WebHello, the new P2D/P3D renderers in 2.0a6 use hardware antialiasing through OpenGL. You set the desired level by calling smooth (n), where n is typically 2, 4, 8, etc., and depends on your video card. 8X should give you a quality level similar to that of JAVA2D, but it can be expensive specially on older/integrated cards. thanks andres. chive wingman 2018
