```
    Description copied from interface: Renderer
    
    Renders count meshes, with the geometry data supplied and per-instance data supplied. The shader which is currently set with setShader is responsible for transforming the input vertices into clip space and shading it based on the given vertex attributes. The integer variable gl_InstanceID can be used to access the current instance of the mesh being rendered inside the vertex shader. If the instance data is non-null, then it is submitted as a per-instance vertex attribute to the shader.
    
    Specified by:
    
    renderMesh in interface Renderer
    
    Parameters:
    
    mesh - The mesh to render
    
    lod - The LOD level to use, see Mesh.setLodLevels(com.jme3.scene.VertexBuffer[]).
    
    count - Number of mesh instances to render
    
    instanceData - When count is greater than 1, these buffers provide the per-instance attributes.
  - setMainFrameBufferSrgb
```
public void setMainFrameBufferSrgb(boolean enableSrgb)
```
    Description copied from interface: Renderer
    
    Specifies whether color values in the main framebuffer are in SRGB format.
    If enabled, color values rendered to the main framebuffer undergo linear -> sRGB conversion.
    This is identical to FrameBuffer.setSrgb(boolean) except it is toggled for the main framebuffer instead of an offscreen buffer.
    This should be set together with Renderer.setLinearizeSrgbImages(boolean)
    As a shorthand, the user can set AppSettings.setGammaCorrection(boolean) to true to toggle both Renderer.setLinearizeSrgbImages(boolean) and Renderer.setMainFrameBufferSrgb(boolean) if the Caps.Srgb is supported by the GPU.
    
    Specified by:
    
    setMainFrameBufferSrgb in interface Renderer
    
    Parameters:
    
    enableSrgb - true for sRGB colorspace, false for linear colorspace
    
    See Also:
    
    FrameBuffer.setSrgb(boolean), Caps.Srgb
  - setLinearizeSrgbImages
```
public void setLinearizeSrgbImages(boolean linearize)
```
    Description copied from interface: Renderer
    
    If enabled, all images with the sRGB flag set shall undergo an sRGB to linear RGB color conversion when read by a shader.
    The conversion is performed for the following formats: - Image.Format.RGB8 - Image.Format.RGBA8 - Image.Format.Luminance8 - Image.Format.Luminance8Alpha8 - Image.Format.DXT1 - Image.Format.DXT1A - Image.Format.DXT3 - Image.Format.DXT5
    For all other formats, no conversion is performed.
    If this option is toggled at runtime, textures must be reloaded for the change to take effect.
    
    Specified by:
    
    setLinearizeSrgbImages in interface Renderer
    
    Parameters:
    
    linearize - If sRGB images undergo sRGB -> linear conversion prior to rendering.
    
    See Also:
    
    Caps.Srgb
  - generateProfilingTasks
```
public int[] generateProfilingTasks(int numTasks)
```
    Description copied from interface: Renderer
    
    Generates a pool of gpu queries meant to use as profiling tasks.
    
    Specified by:
    
    generateProfilingTasks in interface Renderer
    
    Parameters:
    
    numTasks - the number of task ids to generate
    
    Returns:
    
    an array of tasks ids.
  - startProfiling
```
public void startProfiling(int taskId)
```
    Description copied from interface: Renderer
    
    Starts a time profiling task on the GPU. This will profile all operations called between startProfiling and stopProfiling
    
    Specified by:
    
    startProfiling in interface Renderer
    
    Parameters:
    
    taskId - the id of the task to start profiling.
  - stopProfiling
```
public void stopProfiling()

  - getProfilingTime
```
public long getProfilingTime(int taskId)
```
    Description copied from interface: Renderer
    
    Returns the time in nanoseconds elapsed for the task with the given id. Note that the result may not be available right after stopProfiling has been called. You need to check if the result is available with isTaskResultAvailable. Also note that it's guaranteed that the result will be available on next frame. If you use getProfilingTime on the next frame you called stopProfiling, you don't need to check the result availability with isTaskResultAvailable
    
    Specified by:
    
    getProfilingTime in interface Renderer
    
    Parameters:
    
    taskId - the id of the task given by startProfiling.
    
    Returns:
    
    the time in nanosecond of the profiling task with the given id.
  - isTaskResultAvailable

    true for conversion, false for no conversion
