76    <div class="section">
77<p>Immediately creates a floating point constant register command in the command buffer.</p><p>In some cases, performance may be increased by directly generating shader variable commands. To use this function, you must first use the <a href="../../../../nn/gd/CTR/ShaderStage/CreateShaderPipeline.html"><CODE>CreateShaderPipeline</CODE></a> function to specify unmanaged shader variables. (Shader variables that are not set for direct output are automatically re-uploaded in render functions when updates or shader settings are made. )<BR>Command formats that can be entered into the command buffer by the <CODE>SetFloatConstantBuffer</CODE> function are: <br /> 0x00000000 [Reserved] <br /> 0x00000004 [Reserved] <br /> 0x00000008 constantBufferSrc[3] <br /> 0x0000000c [Reserved] <br /> 0x00000010 constantBufferSrc[2] <br /> 0x00000014 constantBufferSrc[1] <br /> 0x00000018 constantBufferSrc[0] <br /> 0x0000001c constantBufferSrc[7] <br /> 0x00000020 constantBufferSrc[6] <br /> 0x00000024 constantBufferSrc[5] <br /> 0x00000028 constantBufferSrc[4] <br /> 0x0000002c constantBufferSrc[11] <br /> 0x00000030 constantBufferSrc[10] <br /> 0x00000034 constantBufferSrc[9] <br /> 0x00000038 constantBufferSrc[8] <br /> 0x0000003c ... <br /> 0x00000040 .. <br /> 0x00000044 . <br /></p><!-- write here --></div>
