Detailed Description

Qt RHI-based 3-D renderer managing scene objects, lighting, camera, and render pipeline for brain visualization.

BrainRenderer handles the low-level RHI rendering logic, managing pipelines, shaders, and draw calls for brain surfaces.

beginFrame()

void BrainRenderer::beginFrame	(	QRhiCommandBuffer *	cb,
		QRhiRenderTarget *	rt )

Begin a rendering frame/pass. Clears the target.

Parameters

[in]	cb	Command buffer to record to.
[in]	rt	Render target to draw into.

Definition at line 279 of file brainrenderer.cpp.

endFrame()

void BrainRenderer::endFrame

(

QRhiCommandBuffer *

cb

)

End the rendering frame/pass.

Parameters

[in]

cb

Command buffer.

Definition at line 298 of file brainrenderer.cpp.

initialize()

void BrainRenderer::initialize	(	QRhi *	rhi,
		QRhiRenderPassDescriptor *	rp,
		int	sampleCount )

Initialize resources (shaders, pipelines) for the given RHI and render pass. Ensures pipelines for all supported modes are created.

Parameters

[in]	rhi	Pointer to QRhi instance.
[in]	rp	Render pass descriptor.
[in]	sampleCount	MSAA sample count.

Definition at line 123 of file brainrenderer.cpp.

renderDipoles()

void BrainRenderer::renderDipoles	(	QRhiCommandBuffer *	cb,
		QRhi *	rhi,
		const SceneData &	data,
		DipoleObject *	dipoles )

Render dipoles using instanced rendering.

Parameters

[in]	cb	Command buffer.
[in]	rhi	QRhi pointer.
[in]	data	Scene uniforms.
[in]	dipoles	Pointer to DipoleObject.

Definition at line 372 of file brainrenderer.cpp.

renderNetwork()

void BrainRenderer::renderNetwork	(	QRhiCommandBuffer *	cb,
		QRhi *	rhi,
		const SceneData &	data,
		NetworkObject *	network )

Render a connectivity network using instanced rendering. Renders both node spheres and edge cylinders as two draw calls.

Parameters

[in]	cb	Command buffer.
[in]	rhi	QRhi pointer.
[in]	data	Scene uniforms.
[in]	network	Pointer to NetworkObject.

Definition at line 418 of file brainrenderer.cpp.

renderSurface()

void BrainRenderer::renderSurface	(	QRhiCommandBuffer *	cb,
		QRhi *	rhi,
		const SceneData &	data,
		BrainSurface *	surface,
		ShaderMode	mode )

Render a single surface. Must be called between beginFrame and endFrame.

Parameters

[in]	cb	Command buffer.
[in]	rhi	QRhi pointer.
[in]	data	Scene uniforms (MVP, light, etc).
[in]	surface	Pointer to surface to draw.
[in]	mode	Shader mode to use for this surface.

Definition at line 305 of file brainrenderer.cpp.

updateSceneUniforms()

void BrainRenderer::updateSceneUniforms	(	QRhi *	rhi,
		const SceneData &	data )

Set uniforms that are shared for the entire frame.

Parameters

[in]

data

Scene uniforms (MVP, light, etc).
