Err Unable To Render Offscreen Image
I attached the updated sample. We just experienced it with Media 7.x-2.0-alpha2 and File Entity 7.x-2.0-alpha3. These limits can be queried via glGetIntegerv with the argument GL_MAX_VIEWPORT_DIMS.

What I've learned leads me to change the status of this from a bug to a support request (and set it's priority to 'normal'). Tecplot seems to have an easier time with NVIDIA cards than ATI cards. Whatever the issue is, it did not surface with 0.14. Rendering into the GLX pixmap may then begin. http://www.tecplottalk.com/forums/viewtopic.php?t=279
Error: Could not load media object This happened for all three media elements embedded in the single node's description. The reason that a FBO has multiple color attachement points is to allow to render the color buffer to multiple destinations at the same time. glGetRenderbufferParameteriv() void glGetRenderbufferParameteriv(GLenum target, GLenum param, GLint* value) You also get various parameters of the currently bound renderbuffer object. Introduction Normally, OpenGL is used for rendering into a window which is displayed on your computer's screen.
Since this error is most often referring to one (or a handful) or specific files that can't be loaded, that tells you the problem is with that specific file (or something Tagged with → antialiasing • buffer • graphics • image • performance • rendering • visual Share → Tweet Recent Posts Determining number of Cells in an Unblanked region Tecplot error Log in or register to post comments Comment #24 Rob_Feature CreditAttribution: Rob_Feature commented December 5, 2016 at 2:26pm Just a note that the fix in #2831810: media wysiwyg tokens with html tex target: GL_TEXTURE_2D textureId, // 4.
Fully clearing the caching solved the issue with the checkbox enabled for us. Therefore, in order to unbind the current framebuffer (FBO), use ID 0 in glBindFramebuffer(). There are multiple color attachment points (GL_COLOR_ATTACHMENT0,..., GL_COLOR_ATTACHMENTn), one depth attachment point (GL_DEPTH_ATTACHMENT), and one stencil attachment point (GL_STENCIL_ATTACHMENT) in a framebuffer object. This "multiple render targets" (MRT) can be accomplished by GL_ARB_draw_buffers extension.
The actual number of auxiliary buffers available can be queried with glGetIntegerv(GL_AUX_BUFFERS, numBuffers). void glBlitFramebuffer(GLint srcX0, GLint srcY0, GLint srcX1, GLint srcY1, // source rectangle GLint dstX0, GLint dstY0, GLint dstX1, GLint dstY1, // destination rect GLbitfield mask, GLenum filter) glBlitFramebuffer() copies But it works for us! The first parameter must be GL_RENDERBUFFER.
How do I fix this? ID 0 is reserved for OpenGL. There is one caveat to this utility library: glRasterPos, glDrawPixels and glBitmap may be troublesome. I tried different image formats (png, jpeg, bmp, tiff).
GLenum glCheckFramebufferStatus(GLenum target) glCheckFramebufferStatus() validates all its attached images and framebuffer parameters on the currently bound FBO. Pros: No window system or operating system dependencies Cons: Only available in Mesa Probably no chance of hardware accelerated rendering Mesa's off-screen rendering interface is quite simple. You can query the maximum number of color attachement points with GL_MAX_COLOR_ATTACHMENTS, which are supported by a graphics card. Microsoft OpenGL Off-Screen Rendering OpenGL for Windows supports off-screen rendering into Windows device-independent bitmaps.

A traditional way of render-to-texture is to draw a scene to the framebuffer as normal, and then copy the framebuffer image to a texture by using glCopyTexSubImage2D(). If it's possible for you to get 12.1 then I would recommend that because it looks like the 10.3 version doesn't work for this approach. Is there any dependencies on the dll versions?
However, there may not be enough memory available in the frame buffer for some or any of those fbconfigs. In order to activate multisample anti-aliasing mode for rendering to a FBO, you need to prepare and attach multisample images to a FBO's color and/or depth attachement points. Setup a perspective or orthographic projection with trFrustum or trOrtho.
Creating Frame Buffer Object (FBO) Creating framebuffer objects is similar to generating vertex buffer objects (VBO).
The target parameter should be GL_FRAMEBUFFER.

thx in advance.. The size of the chart, grid and image weren't matching up so the chart seemed to render with an offset of some kind. See the trdemo1.c program for example usage.
