The matrix that maps S to this point for every S is This matrix can be used if you first translate the world so that the light is at the origin. You're done. Source

Learn more A web application is accessed by web browsers over a network. After you've queried and cleared the current error code, or if there's no error to begin with, glGetError() returns GL_NO_ERROR. Be sure to reenable the depth test and disable the stencil test before additional polygons are drawn. (See "Selecting Color Buffers for Writing and Reading,""Depth Test," and "Stencil Test" in Chapter This game generates some incredibly interesting patterns given different initial configurations. (See Martin Gardner, "Mathematical Games," Scientific American, vol. 223, no. 4, October 1970, p. 120­123.) Figure 14-4 shows six generations https://www.opengl.org/sdk/docs/man/docbook4/xhtml/glGetError.xml

Opengl Get Error String

Every time an error is detected a flag is set and a numeric code is recorded. The offending command is ignored and has no other side effect than to set the error flag. Your first approach might be to draw B after you've drawn A, setting the depth-buffering function to replace on greater or equal. If a stencil buffer is available, the following simpler technique works.

Thanks in advance. Create whichever credentials are appropriate for your project: OAuth: Your application must send an OAuth 2.0 token with any request that accesses private user data. The patch is a bit more complex then described above, thats why I haven’t posted it. Gl Error Codes An app's .plist file contains its bundle identifier.

The vendor-specific information is optional. The API key is safe for embedding in URLs; it doesn't need any encoding. Show instructions The application's Bundle ID is the bundle identifier as listed in the app's .plist file. http://www.lighthouse3d.com/cg-topics/error-tracking-in-opengl/ Is ((a + (b & 255)) & 255) the same as ((a + b) & 255)?

In many cases, such regions indicate design errors where parts of a machine interfere with each other. Gl Error Minecraft You can create OAuth 2.0 credentials for several types of installed applications: Android: You need to specify your Android app's package name and SHA1 fingerprint. Learn more Create and use a server key if your application runs on a server. Configure the stencil buffer to make no stencil value change, but to render only where stencil values are one.

Gl Error 1281

GL_INVALID_VALUE, 0x0501 Given when a value parameter is not a legal value for that function. http://stackoverflow.com/questions/15722803/opengl-shader-error-1282 Just a shot in the dark: but did you ... Opengl Get Error String check your shader got linked without error? Gl Error 1280 Disable the depth-buffer test and its update.

For each polygon, you'll need to clear the stencil buffer, and then draw the outline both in the framebuffer and in the stencil buffer. Return GL_TRUE, if it is; GL_FALSE, if it isn't. Here is a routine to help finding those OpenGL errors. keytool -exportcert -alias androiddebugkey -keystore path-to-debug-or-production-keystore -list -v Note: For the debug.keystore, the password is android. Opengl Error 1282

The following is a slightly more complex version that distorts the image using the functions x(i,j) and y(i,j): glShadeModel(GL_FLAT); for (j=0; j < n; j++) { glBegin(GL_QUAD_STRIP); for (i=0; i <= For details, see http://oss.sgi.com/projects/FreeB/. In many cases, a compromise is possible that allows you to draw the character with a few gray levels between black and white (say, two or three), and the resulting font Be aware that you can run out of identifiers if there are too many objects in the scene.

Where 0 appears in Figure 14-1, nothing is drawn in the framebuffer. Glgeterror Example For your convenience, the headings are listed and explained briefly here. With the polygon offset, the interior recedes just enough that the highlighted edges are drawn without unpleasant visual artifacts.

Error Handling The truth is, your program will make mistakes.

Here's the OAuth2.0 scope information for the Google URL Shortener API: https://www.googleapis.com/auth/urlshortener To request access using OAuth2.0, your application needs the scope information, as well as information that Google supplies when For example, suppose you want to fade to black in 16 steps. The values under 0, 1, 4, 5, 6, 7, and 8 must be cleared to the "dead" color. Glgeterror 1280 Also I have double checked that the program->getHandle() is pointing to something that looks valid.

For detailed information about flows for various types of applications, see Google's OAuth2.0 documentation. After that, you can skip ahead to the section describing whichever action you would like to perform. Enable the depth buffer for writing, and render B. locationType, if present, specifies what part of the request has an error.

How to compose flowering plants? Example 14-1 : Querying and Printing an Error

GLenum errCode; const GLubyte *errString; if ((errCode = glGetError()) != GL_NO_ERROR) { errString = gluErrorString(errCode); fprintf (stderr, "OpenGL Error: %s\n", errString); } Note: The value of this symbolic constant is guaranteed to be 0. Reworded it now. –Reto Koradi Jul 1 '14 at 15:37 No worries, just pointing out the optimization caveat for future readers. –genpfault Jul 1 '14 at 16:22

For example, if you're drawing a model of a molecule made of spheres, you might have an image of a beautifully rendered sphere and its associated depth-buffer values that were calculated Then when you fill the interior, enable drawing only where the stencil buffer is still clear. Also, the GLU defines the error codes GLU_INVALID_ENUM, GLU_INVALID_VALUE, and GLU_OUT_OF_MEMORY, which have the same meaning as the related OpenGL codes.

I didn't expect the shader compiler may do that, It took me by surprise. –Hatoru Hansou Nov 10 '15 at 16:32 add a comment| Your Answer draft saved draft discarded For example, to expand http://goo.gl/fbsS, send the following request: GET https://www.googleapis.com/urlshortener/v1/url?shortUrl=http://goo.gl/fbsS For instance, you could issue the following curl command: curl 'https://www.googleapis.com/urlshortener/v1/url?shortUrl=http://goo.gl/fbsS' If successful, the response will look like: { "kind": To make the problem more concrete, assume that the original image is m pixels by n pixels, with coordinates chosen from [0, m-1] ´ [0, n-1]. Note: If running from client to server, such as when performing indirect rendering with the OpenGL extension to the X Window System, the client and server may be different versions.

GL_RENDERER returns an identifier of the renderer, which is usually the hardware platform. For example, if this OpenGL implementation is from the fictitious XYZ Corporation, the string returned might be 1.1.4 XYZ-OS 3.2 which means that this implementation is XYZ's fourth release of an To create an API key, click Create new Key and select the appropriate key type. The examples are in no particular order and aren't related to each other.

For example, reason will be "required" or "invalid" if some field was missing or malformed. The errors are presented as an error code. iOS: You need to specify the app's Bundle ID and App Store ID. This can be useful for writing applications that are backward compatible with earlier versions of OpenGL. "Extensions to the Standard" presents techniques to identify and use vendor-specific extensions to the OpenGL

In RGBA mode, define three different character bitmaps, corresponding to where 1, 2, and 3 appear in Figure 14-1.
