textures

I am making a 360 viewer in unity, to view a 360 photo I used to have a cubemap attached to a skybox, and it worked great. But the weight of the cubemaps forced me to switch to textures. All of the 360 viewer tutorials say to just put a sphere with a shader on it, and put the camera inside. When I do this, it doesn't work very well, because when I look to the top or bottom, I see the image warped like so: (The chairs are suppossed to look normal) It did not happen when I used a skybox. Does any one know why is this happening? Thank you very much! The shader you choose does not handle

This question is related to this question . The answer shows very nice way to extrude polygons that have holes (see the excellent live example ). The main learning of the answer was that paths in three.js (r58) cannot have more than one moveTo command and it have to be in the start of the path, which means that path have to be broken by moveTos, so that moveTo start always a new path. Extruding in three.js means that 2D paths are converted to 3D shapes using possible beveling. It is suitable for extruding texts to make 3D letters and words, but can be used also to extrude custom paths. Now

After making a few changes in my application, my textures are no longer showing. So far I've checked the following: The camera direction hasn't changed. I can see the vectors (when colored instead of textured). Any usual suspects? You may want to check the following: glEnable(GL_TEXTURE_2D); presence glBindTexture(GL_TEXTURE_2D, texture[i]); and glBindTexture(GL_TEXTURE_2D, 0); when you don't need texture anymore A few more things to check: glColorMaterial(...); To make sure colors aren't overwriting the texture glEnable/glDisable(GL_LIGHTING); Sometimes lighting can wash out the texture

I have a texture which has only 1 channel as it's a grayscale image. When I pass the pixels in to glTexImage2D, it comes out red (obviously because channel 1 is red; RGB). glTexImage2D( GL_TEXTURE_2D, 0, GL_RGBA, dicomImage->GetColumns(), dicomImage->GetRows(), 0, GL_RGBA, GL_UNSIGNED_BYTE, pixelArrayPtr); Do I change GL_RGBA? If so, what to? Change it to GL_LUMINANCE. See http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/teximage2d.html It appears that I should use GL_LUMINANCE instead of GL_RGBA for the 3rd argument. Edit (in reply to comments): When I set the 7th

I'm trying to break up the repetition in my texture by applying a bump map which repeats much less frequently. Unfortunately, it seems to take on the repeat value of 'landTexture' below (64), instead of the value I set it to (1). landTexture.wrapS = landTexture.wrapT = THREE.RepeatWrapping; landTexture.repeat.set(64, 64); bumpTexture.wrapS = bumpTexture.wrapT = THREE.RepeatWrapping; bumpTexture.repeat.set(1, 1); var m = new THREE.MeshPhongMaterial({map:landTexture, ambient: 0x552811, specular: 0x333333, shininess: 25, bumpMap: bumpTexture, bumpScale: 1, metal: false }); If I comment out map

I am using this code to give multiple effect on bitmap that is on GlSurfaceView. apply-effects-on-image-using-effects Now, I want to save the bitmap. They have given the code to save the bitmap but with that, whole GlSurfaceView is going to be saved as bitmap image. Instead I want to save only bitmap area to save as Image. There is method that takes pixels and make bitmap from that and also make image. e.g.: public Bitmap takeScreenshot(GL10 mGL) { final int mWidth = mEffectView.getWidth(); final int mHeight = mEffectView.getHeight(); IntBuffer ib = IntBuffer.allocate(mWidth * mHeight);

I am trying to change a cube image at run time by selecting an option from Select Form element. When running the code, the image changes after selecting, but the previous cube and image stays in the scene. How I clear / refresh / update the scene properly when changing the material / image / texture. <div id = "container"></div> <form id = "changesForm"> Cube Image: <br> <select id = "cubeImage"> <option value = "random">Random</option> <option value = "image1">First Image</option> <option value = "Image2">Second Image</option> </select> <br> </form> <script type = "text/javascript"> window
