DirectX - Is it Using only left angle triangles?

22 October 2012 - 11:21 PM

Hi,

DirectX is using Left handed co- ordinate system, so Can we say DirectX Using only left angle triangles?, or is there any other reasons for that, or it is using both (left angle and right angle) angle triangles?.


Thanks,

Carve Library - Rendering in DirectX Problem

26 September 2012 - 10:18 PM

Hi

I am using Carve library for my experiment project in DirectX, and the results are coming good, but when i am rendering into my DirectX code, the output mesh seems not looking good (the visual only), is it because of my lighting?, i am using directional light with phong shade (a simple light), when i export the output (.obj format), and opens it in 3D Studio Max, in there also it is looking not good, but with "Object Smooth Groups" Option Enabled in 3ds max Import Dialog, then it is rendered good. And in "Carve Viewer" also, the results looking good, what do i do?, is there a problem with my lighting?, or is there a option in carve library itself?, or any "Smoothing functions" are needed before rendering it? .

Any Suggestions?

Thanks.

I attached the pictures

Circular selection of sphere vertices

19 December 2011 - 06:58 AM

Hi all,


I am doing a small experiment with the sphere in directx, i just created a sphere thru sin, cos way, and i have to select the vertices in that sphere in a circular manner around the mouse click, but its not selecting the vertices in the circular manner, i did the same for the simple plane, its worked correctly , i dont know what is the problem , can you help me with this?


thanks.

directx NURBS curve to Beveled surface

25 August 2010 - 02:33 AM

Hi,

I implemented the NURBS curve for my application, from that i need to implement the beveled surface (a surface from the closed curve), is there any specified logic or algorithm is there?, or we have to do it ourselves?, in a website they specified first we have to analyze the x,y (or any other two coordinates of vertices) positions of the vertices and then we have to check the cells they are residing, (cells means X Grid and Y Grid), based on the cells we have to implement the Bevel Surface of the NURBS curve, is it a Good way to do it?, anyone knows any better way than this?

Thanks,
