When using this code, there are some corruption in the display, surface "patches" are not rendered appropriately when displaying against "itself", for example a front facing polygon of a cone or cylinder which is displayed against a back" face of the same cone or cylinder.
To achieve real transparency at a fast rate is hard. To get exact picture , you need to sort triangles from back to front , based your camera vector. Also sometiems , if triangles overlap , you need to splitup it.
The best way to do this is by implementing BSP tree. Using that you can do both front-to back or back-to-front rendering. I would suggest you to look into that first.
In general for a scene , i do like this ( for fake transparency )
1. Render all opaque objects
2. Sort triangles based on their material transparency.
3. Draw triangles which having lesser transparency level first followed by others.
I think this[^] has the answer you're looking for (particularly answer 4). It isn't as simple as it seems and the other solutions I've seen simply set a transparent replacement colour, which is going to result in popping pixels if any part of your rendered objects happen to contain that colour.
u may need to used blending. opengl supports different blending operation between source and destinations. u can use the function glBlendFunc(..) to define the operations. first u need to enable
blending by calling glEnable(GL_BLEND)
I think this problem occurs because of x and y of points because when I change the points, the shape will fill correctly.
Here is the code:
publicpartialclass Form1 : Form
privatevoid Form1_Paint(object sender, PaintEventArgs e)
Graphics g = e.Graphics;
GraphicsPath gp = new GraphicsPath(FillMode.Winding);
gp.AddLine(new PointF(290, 170),new PointF(98, 128));
gp.AddLine(new PointF(110, 170), new PointF(290, 170));
gp.AddLine(new PointF(110, 170), new PointF(98, 128));
g.FillPath(new SolidBrush(Color.Red), gp);
I want a tool to plot real time graph for .net platform.The data which has to be plotted is continuously coming in some time interval.Is there any tool available?
Also Performance issue is there.Performance also matters when I am using the tool.
Thanks in adv...
Since your question mentions the fact that you want to do this in .NET I would expect the .NET Framework forum would be a good start. I note that you have been a CP member for over a year now so you should be familiar with the posting guidelines.
Just say 'NO' to evaluated arguments for diadic functions! Ash
What is the proper way to cause dc to release bitmap without assigning another "real" resource (return the dc to its freshly created state) so that another dc in another subroutine can select mybitmap?
