textures

问题 I'am trying to make libgdx game, adn i've got 2 problems now: 1. When im using camera.setToOrtho(false, GAME_WIDTH, GAME_HEIGHT); my textrure of player is distored, one eye is bigger than another. 2. Im using this camera and viweport: camera= new OrthographicCamera(GAME_WIDTH,GAME_HEIGHT); camera.setToOrtho(false, GAME_WIDTH, GAME_HEIGHT); viewport = new StretchViewport(GAME_WIDTH,GAME_HEIGHT,camera); and when i do : touchPos.set(Gdx.input.getX(1),Gdx.input.getY(1),0); game.camera.unproject

问题 EDIT: I added the following code in both the dealloc and cleanup method of the previous scene (the one from which I call replaceScene but it does not have any effect. Even after 1/2/5 seconds from when InstructionScene has being created the memory does still contain the assets from the previous scene. The only way to force the removal of those is to remove them from the new scene 0.1f seconds after the scene is being created (via a Callback). This is kind of weird. Here is the code of the

问题 How to use the OES_texture_float extension? I do not understand that it is necessary to specify the arguments the function texImage2D. var fb=gl.createFramebuffer(); gl.bindFramebuffer(gl.FRAMEBUFFER, fb); var rb=gl.createRenderbuffer(); gl.bindRenderbuffer(gl.RENDERBUFFER, rb); gl.renderbufferStorage(gl.RENDERBUFFER, gl.DEPTH_COMPONENT16,size[0],size[1]); gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.DEPTH_ATTACHMENT,gl.RENDERBUFFER, rb); var texture=gl.createTexture(); gl.bindTexture(gl

问题 TexturePaint Problems I am currently making a 2D game using texturepaints. One significant problem I encountered was the fact that filling rectangles with the graphics2D setPaint method set to a texture paint is extremely slower than filling a rectangle with a base color. Is there possibly any other way to speed up painting by creating a custom class similar to Texturepaint that paints much faster? At this point I really don't know what to do because my fps is stuck at around 18-23fps. EDIT :

问题 I wrote this code while following the tutorial for SFML in C++: #include <SFML/Graphics.hpp> int main() { sf::RenderWindow window(sf::VideoMode(600, 400), "Sandstorm"); while (window.isOpen()) { sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } window.clear(sf::Color::Black); sf::Texture back; if (!back.loadFromFile("greenBack.png")) return 1; sf::Sprite sprite; sprite.setTexture(back); window.draw(sprite); window.display(); } return 0;

问题 EDIT 4: I added a breakpoint to CCSpriteFrameCache spriteFrameByName method and cannot step over the following step (its clear to me that somehow the spriteFrames gets deleted from the CCSpriteFrameCache): EDIT 3: Before voting to close the question actually PLEASE TRY the code below (EDIT2) using Cocos2d 2.0 and the file and plist file attached. EDIT 2: I created a brand new GameScene test class so you can all try out the issue. It crashes as soon as the animation starts to repeat. I update

问题 I've tried a simple program that dynamically generates a texture and map it to a quad using NDK. Everything is fine on an emulator but failed on real devices. Here is my code: private static class Renderer implements GLSurfaceView.Renderer { @Override public void onDrawFrame(GL10 gl) { nativeDrawFrame(); } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { nativeInit(width, height); } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { // do nothing... }

问题 I have scar textures and I want to get rid of the background skin colour by using alpha blending. However, I have problems with changing the opacity of individual pixels of specific textures. What is the easiest way to have textures with transparent background? I am using C++ and openGL. I am using a BMP picture format and I am trying to map that scar texture onto the face but background colour of scar texture seems ugly on the face, so I want to remove that part and have only scar texture

问题 From what I've been seeing around the internet, this problem can't really be solved with my approach. I am currently writing a program that uses a selection buffer pass over all the objects in the scene. However, one of the objects is a texture in which a large part of it has alpha 0. It works fine when rendering, the alpha values are not displayed, but when in selection mode, the alpha test is skipped, and hovering the mouse over the transparent areas selects the object instead of whatever
