Detailed Description

Drawable geometric model using VK vertex buffers.

Supports loading from OBJ file data. Contains positions as well as optional normals, UVs, and tangent vectors

Member Function Documentation

static NvModelVK* NvModelVK::CreateFromObj	(	NvVkContext &	vk,
		uint8_t *	data,
		float	scale,
		bool	computeNormals = false,
		bool	computeTangents = false
	)			[static]

Create a renderable model from OBJ data.

Parameters:

[in]	vk	Vulkan device/queue to render to
[in]	data	pointer to OBJ file data
[in]	scale	the target radius to which we want the model scaled, or <0 if no scaling should be done
[in]	computeNormals	indicate whether per-vertex normals should be estimated and added
[in]	computeTangents	indicate whether per-vertex tangent vectors should be estimated and added

Returns:

a pointer to the new model

static NvModelVK* NvModelVK::CreateFromPreprocessed	(	NvVkContext &	vk,
		uint8_t *	data
	)			[static]

Create a renderable model from a preprocessed "NVM" file, which is much faster and more efficient to load than OBJ.

Parameters:

[in]	vk	Vulkan device/queue to render to
[in]	data	pointer to NVM file data

Returns:

a pointer to the new model

void NvModelVK::Draw

(

VkCommandBuffer &

cmd

)

Draw to an open command buffer.

Parameters:

[in]

the

command buffer to draw into

VkPipelineInputAssemblyStateCreateInfo& NvModelVK::getIAInfo

(

)

[inline]

Get the Input Assembly state for creating a rendering pipeline object for this model.

Returns:

the IAStateInfo for this model

(

)

[inline]

Get the index count (for advanced rendering).

Returns:

the index count

NvModel* NvModelVK::getModel

(

VkPipelineVertexInputStateCreateInfo& NvModelVK::getVIInfo

(

)

[inline]

Get the Vertex input state for creating a rendering pipeline object for this model.

Returns:

the VIStateInfo for this model
