We can already have textbox using ImGUI but when typing wasd for example, it will also trigger the callbacks attached to the key events W, A, S and D.

See ocornut/imgui#703 and ocornut/imgui#1219 (comment) if needed :D

Good luck, I love your work!

Instead of the common Fresnel calculation, Brian Karis suggests using a spherical gaussian approximation, which he deems more efficient with unnoticeable differences.

As such, the current Fresnel calculation:

vec3 fresnel = baseReflectivity + (1.0 - baseReflectivity) * pow(1.0 - cosTheta, 5.0);

would become:

vec3 fresnel = baseReflectivity + (1.0 - baseReflectivity) * pow(2.0, (-5.55473 * cosTheta - 6.98316) * cosTheta);

In RaZ's case, this actually fixes black artifacts when the light's position is strictly equivalent to the camera's (which should not happen in real life cases):

This optimization should probably be investigated, as the artifacts may come from a small blunder in the implementation.

Why no llvmpipe rendering?

I'm trying to use RaZ in a simulator project.

I need the ability to transform Meshes imported from a Gltf file in Runtime.

For example:

We have a model of a clock:

node1 {transform, mesh} - watch case
node2 {transform, mesh} - hour hand
node3 {transform, mesh} - minutes hand
node4 {transform, mesh} - seconds hand

After exporting the model, you need to be able to:

model.getNodeTransform(node2.name).setRotation(hours_value)
model.getNodeTransform(node2.name).setRotation(minutes_value)
model.getNodeTransform(node2.name).setRotation(seconds_value)

Possible Solution.

In RaZ:

Add two modules: GltfSceneFormat (from GltfLoad.cpp) SceneRenderer (new component).

// GltfSceneFormat.cpp

void loadVertices(...)
{
...
//if (transform.has_value()) {
// for (Vertex& vert : submesh.getVertices()) {
// vert.position = transform->getPosition() + transform->getRotation() * (vert.position * transform->getScale());
// vert.normal = (transform->getRotation() * vert.normal).normalize();
// vert.tangent = (transform->getRotation() * vert.tangent).normalize();
// }
//}
}

std::vector<std::optional> loadTransforms(
SceneRenderer & sceneRenderer,
const std::vectorfastgltf::Node& nodes,
std::size_t meshCount)
{
std::vector<std::optional> transforms;
transforms.resize(meshCount);

for (const fastgltf::Node& node : nodes)
{
Transform transform = loadTransform(node);
sceneRenderer.m_transforms.emplace_back(transform);
//computeNodeTransform(node, std::nullopt, nodes, transforms);
}

return transforms;
}

void loadNodes(SceneRenderer & sceneRenderer, const std::vectorfastgltf::Node& nodes)
{
unsigned long transformIndex = 0;

for (auto & node_ : nodes)
{     
    SceneRenderer::Node node;
    node.name = node_.name.c_str();
    node.transformIndex = transformIndex;
    transformIndex++;
    if (node_.meshIndex.has_value())
        node.meshIndex = node_.meshIndex.value();
    for (auto child : node_.children)
    {
        node.children.emplace_back(child);
    }
    sceneRenderer.m_nodes.emplace_back(node);
}

}

std::pair<Mesh, MeshRenderer> loadMeshes(...)
{
...
Mesh loadedMesh;
MeshRenderer loadedMeshRenderer;
for (const fastgltf::Primitive& primitive : meshes[meshIndex].primitives) {
...
Submesh& submesh = loadedMesh.addSubmesh();
SubmeshRenderer& submeshRenderer = loadedMeshRenderer.addSubmeshRenderer();
...
loadedMeshRenderer.getMaterials().emplace_back(std::move(Material(MaterialType::COOK_TORRANCE)));
...
}
...

}

SceneRenderer load(const FilePath& filePath) {
...
const std::vector<std::optional> transforms = loadTransforms(sceneRenderer, asset->nodes, asset->meshes.size());

loadNodes(sceneRenderer, asset->nodes);

for (auto & node : asset->nodes)
{
if (node.meshIndex.has_value())
{
auto [mesh, meshRenderer] = loadMeshes(asset->meshes, node.meshIndex.value(), asset->buffers, asset->bufferViews, asset->accessors, transforms);
sceneRenderer.m_meshRenderers.emplace_back(std::move(meshRenderer));
}
}

const std::vector<std::optional> images = loadImages(asset->images, asset->buffers, asset->bufferViews, parentPath);

for (auto & meshRenderer : sceneRenderer.m_meshRenderers)
loadMaterials(asset->materials, asset->textures, images, meshRenderer);
...
return sceneRenderer;
}

And:
// RendererSystem.cpp
void RenderSystem::linkEntity(const EntityPtr& entity) {
...
}

void RenderSystem::initialize() {
// add GltfRenderer
registerComponents<Camera, Light, MeshRenderer, SceneRenderer>();
...
// add GltfRenderer
if (entity->hasComponent())
{
auto & gltfrenderer = entity->getComponent();
//for (auto & meshrenderer : gltfrenderer.getMeshRenderers())
for (auto & meshrenderer : gltfrenderer.m_meshRenderers)
updateMaterials(meshrenderer);
}

}

// RenderGph.cpp
void RenderGraph::execute(RenderSystem& renderSystem) {
...

// add GltfRenderer
}
else if (entity->hasComponent())
{
if (!entity->isEnabled() || !entity->hasComponent())
continue;

const auto& gltfRenderer = entity->getComponent<SceneRenderer>();

if (!gltfRenderer.isEnabled())
  continue;
auto m_ = entity->getComponent<Transform>().computeTransformMatrix();
renderSystem.m_modelUbo.sendData(entity->getComponent<Transform>().computeTransformMatrix(), 0);
auto m = entity->getComponent<Transform>().computeTransformMatrix();
gltfRenderer.draw(renderSystem.m_modelUbo, m);

}

In App:

Raz::Entity& clock = world.addEntityWithComponentRaz::Transform();
auto & clockRenderer = clock.addComponentRaz::SceneRenderer(Raz::GltfSceneFormat::load(RAZ_ROOT "assets/watch_case.gltf"));
auto hours = clockRenderer.getTransformNode("hours_hend");
auto minutes = clockRenderer.getTransformNode("hours_hend");
auto seconds = clockRenderer.getTransformNode("hours_hend");

app.run([&] (float deltaTime) {
// get current hours_value, minutes_value, seconds_value
hours.value()->setRotation(hours_value);
minutes.value()->setRotation(minutes_value);
seconds.value()->setRotation(seconds_value);
});

Example implementation in attached files:

This really works.

You are free to use this code as you wish.

After having tried many different things, launching unit tests which require graphics capabilities (using GLFW in this case) always fail. It is yet unknown if this is due to:

• A technical issue of macOS VMs/servers without any available workaround (which doesn't seem like it, since there are reports that it can be done, at least could have been some time ago);
• Something missing concerning the window's initialization: GLFW may need specific settings to be able to start under those conditions;
• Specific arguments to launch Xvfb and/or the tests executable with.

See:

• go-flutter-desktop/go-flutter#186

Note: Xvfb needs the package xquartz to be installed by brew.

It has been pointed out that Cook-Torrance's most common explanations don't include the fact that the Fresnel component is actually symmetric.

See:

Hey there @Razakhel ! 🖐️

Is there a planned roadmap for this framework? Or are there expected timelines when newer features are going to be added?
In addition, is there expected to be features like alpha channel support soon? Or is this project considered to be "abandoned" and will no longer be updated or worked on?

And gratz in advance!

Many resources are available, which need to be tested further:

• Scratchapixel's explanation: https://www.scratchapixel.com/lessons/procedural-generation-virtual-worlds/simulating-sky
• Frostbite's papier on physically-based sky, atmosphere & clouds: https://sebh.github.io/publications/egsr2020.pdf
  • Related presentation: https://www.ea.com/frostbite/news/physically-based-sky-atmosphere-and-cloud-rendering
• GPU Gem about atmospheric scattering: https://developer.nvidia.com/gpugems/gpugems2/part-ii-shading-lighting-and-shadows/chapter-16-accurate-atmospheric-scattering

Just a suggestion.

Hi, the How to build RaZ wiki page has ***Writing in progress.***. I have attached a patch to add instructions for the Building on Linux section.

patch.txt

I think there is an error in file GltfLoad.cpp
Available:

347 if (mat.pbrData.baseColorTexture && images[mat.pbrData.baseColorTexture->textureIndex])
348 matProgram.setTexture(Texture2D::create(*images[mat.pbrData.baseColorTexture->textureIndex]), MaterialTexture::BaseColor);

...

Right:

add const std::vectorfastgltf::Texture& textures as parameter in void loadMaterials

347 if (mat.pbrData.baseColorTexture && textures[mat.pbrData.baseColorTexture->textureIndex].imageIndex)
{
auto imageIndex = textures[mat.pbrData.baseColorTexture->textureIndex].imageIndex.value();
matProgram.setTexture(Texture2D::create(*images[imageIndex]), MaterialTexture::BaseColor);
}

if (mat.emissiveTexture && textures[mat.emissiveTexture->textureIndex].imageIndex)
{
  auto imageIndex = textures[mat.emissiveTexture->textureIndex].imageIndex.value();
  matProgram.setTexture(Texture2D::create(*images[imageIndex]), MaterialTexture::Emissive);
}  

if (mat.occlusionTexture && textures[mat.occlusionTexture->textureIndex].imageIndex) { // Ambient occlusion

  const Image ambientOcclusionImg = extractAmbientOcclusionImage(*images[mat.occlusionTexture->textureIndex]);
  matProgram.setTexture(Texture2D::create(ambientOcclusionImg), MaterialTexture::Ambient);
}

if (mat.normalTexture && textures[mat.normalTexture->textureIndex].imageIndex)
{
  auto imageIndex = textures[mat.normalTexture->textureIndex].imageIndex.value();
  matProgram.setTexture(Texture2D::create(*images[imageIndex]), MaterialTexture::Normal);
}

if (mat.pbrData.metallicRoughnessTexture && textures[mat.pbrData.metallicRoughnessTexture->textureIndex].imageIndex) {
  const auto [metalnessImg, roughnessImg] = extractMetalnessRoughnessImages(*images[mat.pbrData.metallicRoughnessTexture->textureIndex]);
  matProgram.setTexture(Texture2D::create(metalnessImg), MaterialTexture::Metallic);
  matProgram.setTexture(Texture2D::create(roughnessImg), MaterialTexture::Roughness);
}

At least it works correctly for me.
