最近我被告知,通过使用上游 < code> general Intialize () () , Prolog可以创建图形显示,并被告知。
我能请教一下吗?
例如, 如何显示矩形?
rectangle(2, 1, 2, 1). %rectangle(length, width, length width).
我使用Win-Prolog 4.920。

Im 使用 gfx
绘制显示。
display :-
create_display,
window_handler( display, display_handler ),
show_dialog( display ).
create_display :-
wdcreate( display,`Graphics Example`, 70, 50, 1200,510,[ws_sysmenu, ws_caption, ws_popup] ),
wccreate( (display,2),grafix, ``, 10, 10, 1050, 457,[ws_child, ws_border, ws_visible, ws_tabstop] ),
gfx_brush_create(red, 255, 0, 0, solid).
display_handler( _, msg_close, _, close ):-
wclose(display).
display_handler( Win, msg_paint, grafix, _ ) :-
gfx_paint( Win ),
gfx( ( brush = red -> rectangle( 280, 212, 0, 12 ))),
gfx_end( Win ).

I am writing simple hex engine for action-rpg in XNA 3.1. I want to light ground near hero and torches just as they were lighted in Diablo II. I though the best way to do so was to calculate field-of-...
I m trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity ...
I am trying to check the location of a point(px, py) on 2D graph in relation to a line segment (lx1, ly1) (lx2, ly2), using logic of North South East West directions. The logic I have implemented is ...
How can I draw a perpendicular on a line segment from a given point? My line segment is defined as (x1, y1), (x2, y2), If I draw a perpendicular from a point (x3,y3) and it meets to line on point (x4,...
So I m trying to figure out how to implement a method of selecting lines or edges in a drawing area but my math is a bit lacking. This is what I got so far: A collection of lines, each line has two ...
