This new version of GLM is bringing a lot of improvements and maybe too many considering the development time it has required:
|
||||
API exposing SIMD implementation but also some new, safe and feature complet swizzling functions and a new setup API.
|
||||
All this is described in the largely updated <link href="http://glm.g-truc.net/glm-0.9.1.pdf">GLM manual</link>.
|
||||
</paragraph>
|
||||
<paragraph>
|
||||
With the new setup system, GLM detects automatically the compiler settings to adapt its implementation to the flag set at build time.
|
||||
It will automatically enable C++0x features, SSE optimizations and the display configuration informations at build-time.
|
||||
The automatic setup can be overdrive by the GLM user.
|
||||
</paragraph>
|
||||
<paragraph>
|
||||
The SIMD API maintly focus on vec4 and mat4 implementations that are embodied by the types <codeword>simdVec4</codeword> and <codeword>simdMat4</codeword>.
|
||||
The implemention cover most of the common functions, the geometry functions and the matrix functions as described in the GLSL specifications.
|
||||
Because it is hight inefficient to access individual components of a SIMD register, the <codeword>simdVec4</codeword> doesn't allow it.
|
||||
To reflect this constraint, the <codeword>simdVec4</codeword> has to be converted to <codeword>vec4</codeword> first which would be effectively handle
|
||||
by the compiler thank to the function <codeword>simdCast</codeword>.
|
||||
Furthermore, GLM provides some specials functions like simdDot4 that returns a <codeword>simdVec4</codeword> instead of a float
|
||||
with the duplicated dot product value in each components
|
||||
and ensure that no unnecessary component manipulations are performed (typically <codeword>__m128</codeword> to <codeword>float</codeword>
|
||||
and <codeword>float</codeword> to <codeword>__m128</codeword>).
|
||||
This implementation can probably be improve in many ways so don't hesitate to send me some feedbacks.

||||

||||
|
||||
<paragraph>
|
||||
GLM 0.9.1 is not 100% backward compatible with GLM 0.9.0 but mostly advanced usages should be concerned by this compatibility issues.
