I've been playing a bit with the new flash 10 3d possibilities, and found out that rotating a sprite in 3d is fairly easy: var card:Sprite = new MyCard() card.x = 100 card.y = 100 card.z = 200 card.rotationX = -60 addChild(card) Simple and effective, this shows the card rotated with perspective. Now I want to use an orthographic proj...
Using DirectX I'm rendering textured polygons (orthographically) so they act as HUD sprites. Now I'm not sure how would I go about implementing sprite masking in this sytem? So basically say I have a sprite, how can I make it render only in a given portion of the screen which I define? And if a part of it moves outside this portion of t...
Hello. I added Orthographic Camera to my project. I want to show my chart on screen proportional. For example height is 4 and width 4 (region from -2 to 2). I set width to 4 and it perfectly fit my square in widht. but i have problem with height. The chart top and bottom is always out of screen space. Why this happens and how to set to...
Dear all, I'm building a game level editing app as part of a university project. In my application I have multiple viewports, a Perspective viewport and three orthographic views all setup to view the same scene. I've successfuly setup the orthographic views and can translate and scale them to mimic scrolling and zooming. Unfortunately,...
I am rendering textured quads from an orthographic perspective and would like to simulate 'depth' by modifying UVs and the vertex positions of the quads four points (top left, top right, bottom left, bottom right). I've found if I make the top left and bottom right corners y position be the same I don't get a linear 'skew' but rather a ...
I'm writing a 2D game in Opengl. I already set up the orthogonal projection so I can easily know where a quad will end up on screen. The problem is, I also want to be able to map pixels directly to texture coords, so I also applied an orthogonal transformation (using gluOrtho2d) to the texture. Now I can map pixels directly using integer...
I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up spa...
Hi All, I have a scene that stores vertices in 3D space. What i would like to do is render those vertices Orthographically from an isometric perspective. In all of my searching the obvious answer is to use an Orthographic camera like the ones in OpenGL etc. The problem is that i'd like to write this from scratch to help with my under...
We have a mostly 2D game that runs in orthographic mode, but one part shows a 3d model that is rendered in between the other 2D objects. How can I switch to perspective mode, render that model, then switch back to render the other objects in orthographic mode? Kudos if you can show how it's done in OpenGL ES. ...
Hi all, (Mac OS X, Cocoa, C/C++, OpenGL, somewhat mathematically challenged.) Project is a real-time (30fps) poker game, with a 2D view. The OpenGL view is set up for Orthographic projection using glOrtho; the camera is always looking directly down at the cards/table. To date, it's essentially been a 2D image composition engine. My pl...
I need to create whole-sky maps, but Google Earth in Sky mode has limited "zoom out." Is it possible to create an orthographic map projection with Google Earth (or, for that matter, MS Virtual Earth)? Really any of the standard projections will do, although it would be nice to have options. Of course, I could render the projection stat...
