esp::gfx_batch::DepthShader class
#include <esp/gfx_batch/DepthUnprojection.h>

Depth-only shader.

Outputs depth values without projection applied. Can also unproject existing depth buffer if Flag::UnprojectExistingDepth is enabled.

Public types

enum class Flag { UnprojectExistingDepth = 1 << 0, NoFarPlanePatching = 1 << 1 }: Flag.
using Flags = Corrade::Containers::EnumSet<Flag>: Flags.

auto setTransformationMatrix(const Magnum::Matrix4& matrix) -> DepthShader&: Set transformation and projection matrix.
auto setDepthUnprojection(const Magnum::Vector2& depthUnprojection) -> DepthShader&: Set the depth unprojection parameters directly.
auto setProjectionMatrix(const Magnum::Matrix4& matrix) -> DepthShader&: Set projection matrix for unprojection.
auto bindDepthTexture(Magnum::GL::Texture2D& texture) -> DepthShader&: Bind depth texture.
auto flags() const -> Flags: The flags passed to the Constructor.

Flag.

Enumerators
UnprojectExistingDepth	Perform unprojection of an existing depth buffer. If enabled, instead of rendering particular polygons bind a depth texture with bindDepthTexture(). The shader will then render a full-screen triangle and unprojects the depth using an inverse of the matrix passed in setProjectionMatrix().
NoFarPlanePatching	By default, depth values on the far plane are patched to have a value of `0.0f` (instead of `100.0f` or whatever the far plane is set to). This might have some performance penalty and can be turned off with this flag.

Set transformation and projection matrix.

Returns	Reference to self (for method chaining)

Expects that Flag::UnprojectExistingDepth is not set.

Set the depth unprojection parameters directly.

Returns	Reference to self (for method chaining)

Returns	Reference to self (for method chaining)

Bind depth texture.

Returns	Reference to self (for method chaining)

Expects that Flag::UnprojectExistingDepth is set.
