OPENGL 3.3 DRIVER

The following graphics cards and chips specifically support OpenGL 3.0/3.1/3.2/3.3 and should be considered the absolute minimum (note: actually support may be subject to driver availability, OpenGL 3.3 and system hardware support) Understandably what may be easily affordable and acquirable hardware for one personВ may not be for another. In this second part of the discussion on running Blender on older computers we take a look at upgrading incompatible computers and hardwareВ cheaply and where it can generally be acquired. What is the result ? Give 3 different ways to fix this.In first part ofВ вЂњ Will Blender run on older computersвЂќ the minimum requirements necessary to runВ Blender were discussed, namely theВ need for graphics hardware supportingВ and/or compatibility with OpenGL 3.3 or higher (largely as related to Windows OS computers), itself published c.2010.Дesign note: It should be noted that Blender does cater to вЂlegacy hardwareвЂ™ to aВ degree in providing support for components and systems that are almost a decade old (based on OpenGL version supported), a very long time in technological terms. Try not to generate mipmaps in The Compressonator.Do they give different result ? Different compression ratios ? Experiment with the various DDS formats.

OPENGL 3.3 CODE

Change the code at the appropriate place to display the cube correctly.

The DDS loader is implemented in the source code, but not the texture coordinate modification.

In general, you should only use compressed textures, since they are smaller to store, almost instantaneous to load, and faster to use the main drawback it that you have to convert your images through The Compressonator (or any similar tool) Exercices You just learnt to create, load and use textures in OpenGL. You can do this whenever you want : in your export script, in your loader, in your shaderвЂ¦ Conclusion So if you use compressed textures, youвЂ™ll have to use ( coord.u, 1.0-coord.v) to fetch the correct texel. Static const GLfloat g_uv_buffer_data = free ( buffer ) return textureID Inversing the UVsДXT compression comes from the DirectX world, where the V texture coordinate is inversed compared to OpenGL.

OPENGL 3.3 HOW TO

You'll learn shortly how to do this yourself. Here is the declaration of the loading function : So weвЂ™ll write a BMP file loader from scratch, so that you know how it works, and never use it again. But itвЂ™s very simple and can help you understand how things work under the hood.

Knowing the BMP file format is not crucial : plenty of libraries can load BMP files for you. Notice how the texture is distorted on the triangle. These coordinates are used to access the texture, in the following way : This is done with UV coordinates.Д®ach vertex can have, on top of its position, a couple of floats, U and V.

When texturing a mesh, you need a way to tell to OpenGL which part of the image has to be used for each triangle.
