HPS

This is a very simple HPS sample to create a shell using Physically Based Rendering (or PBR).

More details are available about PBR and related properties under the Materials documentation.

Instructions

  1. Add the following code to a CHPSView User Code method in the MFC Sandbox application:

    void CHPSView::OnUserCode3()
{
	PortfolioKey portfolio = Database::CreatePortfolio();
	SegmentKey my_seg = GetCanvas().GetFrontView().GetAttachedModel().GetSegmentKey();
	my_seg.GetPortfolioControl().Push(portfolio);
	{
		auto load_png = [&](const char * file_name, const char * image_name) -> bool {
			HPS::Image::ImportOptionsKit iok;
			iok.SetFormat(HPS::Image::Format::Png);
			ImageKit image_kit = Image::File::Import(file_name, iok);
			ImageDefinition image_def = portfolio.DefineImage(image_name, image_kit);
			TextureDefinition txr_def = portfolio.DefineTexture(image_name, image_def);
			return true;
		};

		load_png("ship.png", "ship");

		load_png("IMAGE_PBR_PATH/chipped-paint-metal/chipped-paint-metal-albedo.png", "chipped-paint-metal-albedo");
		load_png("IMAGE_PBR_PATH/chipped-paint-metal/chipped-paint-ao.png", "chipped-paint-metal-ao");
		load_png("IMAGE_PBR_PATH/chipped-paint-metal/chipped-paint-metal-metal.png", "chipped-paint-metal-metalness");
		load_png("IMAGE_PBR_PATH/chipped-paint-metal/chipped-paint-metal-rough2.png", "chipped-paint-metal-roughness");
		load_png("IMAGE_PBR_PATH/chipped-paint-metal/chipped-paint-metal-normal-dx.png", "chipped-paint-metal-normal");

		GlyphKit glyphKit = GlyphKit();
		glyphKit.SetRadius(0);
		glyphKit.SetOffset(GlyphPoint(0, 0));

		ImageGlyphElement imageGlyphElement;
		imageGlyphElement.SetSource("ship");

		GlyphElementArray glyphElements;
		glyphElements.push_back(imageGlyphElement);
		glyphKit.SetElements(glyphElements);

		portfolio.DefineGlyph("shipGlyph", glyphKit);
	}
	SegmentKey shellSegment = my_seg.Subsegment();
	shellSegment.GetVisibilityControl().SetEverything(false);

	// Insert a small test shell with parameterization
	ShellKey shellKey;
	{
		float const quad_points[] =
		{
			-0.75f, 0.75f, 0.0f,
			0.75f, 0.75f, 0.0f,
			0.75f, -0.75f, 0.0f,
			-0.75f, -0.75f, 0.0f
		};

		int const quad_flist[] =
		{
			4, 0, 1, 2, 3
		};

		float const quad_uvs[] =
		{
			0.0f, 1.0f,
			1.0f, 1.0f,
			1.0f, 0.0f,
			0.0f, 0.0f,
		};

		shellKey = shellSegment.InsertShell(4, (Point const *)&quad_points[0], 5, quad_flist);
		shellKey.SetVertexParametersByRange(0, 8, quad_uvs, 2);
	}

	my_seg.GetVisibilityControl().SetEverything(false).SetFaces(true).SetLights(true);
	my_seg.ReferenceGeometry(shellKey);

	PBRMaterialKit pbr;
	pbr.SetBaseColorMap("chipped-paint-metal-albedo");
	pbr.SetNormalMap("chipped-paint-metal-normal");
	pbr.SetMetalnessMap("chipped-paint-metal-metalness", HPS::Material::Texture::ChannelMapping::Red);
	pbr.SetRoughnessMap("chipped-paint-metal-roughness", HPS::Material::Texture::ChannelMapping::Red);
	pbr.SetOcclusionMap("chipped-paint-metal-ao", HPS::Material::Texture::ChannelMapping::Red);

	my_seg.SetPBRMaterial(pbr);

	my_seg.InsertDistantLight(Vector(0.4174f, 0.2564f, -0.8951f));
}

  2. Download the Chipped Paint Metal PBR Material images archive from FreePBR.com called chipped-paint-metal-ue and install it on your system.

  3. Replace “IMAGE_PBR_PATH” in the code with the actual path to the unzipped Chipped Paint Metal files.

This should result in a scene similar to:

3DF

This is a very simple 3DF sample function to create a shell using Physically Based Rendering (or PBR).

More details are available about PBR and related properties under the Materials documentation.

Instructions

  1. Add the following test function to a HOOPS 3DF application:

    int TestPBR ()
{
	if (!IsShaderDriver()) // make sure driver is ogl or dx11
		return TEST_UNSUPPORTED;

    HC_Open_Segment ("a");
		HC_Open_Segment("image"); {
			HC_Set_Visibility("images=off");
			auto load_png = [](const char * file_name, const char * image_name) -> bool {
				FILE *file = fopen(file_name), "rb");
				if (!file)
					return false;
				fseek(file, 0, SEEK_END);
				int length = ftell(file);
				fseek(file, 0, SEEK_SET);
				unsigned char * buffer = new unsigned char[length];
				fread(buffer, sizeof(unsigned char), length, file);
				fclose(file);
				HC_Insert_Compressed_Image(0, 0, 0, H_FORMAT_TEXT("png, name = %s", image_name), -1, -1, length, buffer);
				delete[] buffer;
				return true;
			};

			if (!load_png("IMAGE_PBR_PATH/sandstonecliff-albedo.png", "sandstonecliff-albedo"))
				return TEST_IMAGE_MISSING;
			if (!load_png("IMAGE_PBR_PATH/sandstonecliff-ao.png", "sandstonecliff-ao"))
				return TEST_IMAGE_MISSING;
			if (!load_png("IMAGE_PBR_PATH/sandstonecliff-metalness.png", "sandstonecliff-metalness"))
				return TEST_IMAGE_MISSING;
			if (!load_png("IMAGE_PBR_PATH/sandstonecliff-roughness.png", "sandstonecliff-roughness"))
				return TEST_IMAGE_MISSING;
			if (!load_png("IMAGE_PBR_PATH/sandstonecliff-normal-ue.png", "sandstonecliff-normal"))
				return TEST_IMAGE_MISSING;
		} HC_Close_Segment();

		HC_Set_PBR_Material("sandstonecliff-albedo", "sandstonecliff-normal", nullptr,
							"sandstonecliff-metalness", 0,
							"sandstonecliff-roughness", 0,
							"sandstonecliff-ao", 0,
							nullptr,
							1.0, 1.0, 1.0, 1.0, 1.0,
							nullptr);
		HC_Insert_Distant_Light(1, 1, -1);

		HC_Open_Segment("shell"); {
			float const quad_points[] = {
				-0.75f, 0.75f, 0.0f,
				0.75f, 0.75f, 0.0f,
				0.75f, -0.75f, 0.0f,
				-0.75f, -0.75f, 0.0f
			};
			int const quad_flist[] = {4, 0, 1, 2, 3};
			float const quad_uvs[] = {
				0.0f, 1.0f,
				1.0f, 1.0f,
				1.0f, 0.0f,
				0.0f, 0.0f,
			};

			HC_Set_Visibility("no edges, no markers");
			HC_KEY	shell_key = HC_Insert_Shell(4, quad_points, 5, quad_flist);
			HC_MSet_Vertex_Parameters(shell_key, 0, 4, 2, quad_uvs);
		} HC_Close_Segment();
	
    HC_Close_Segment();

    return TEST_COMPLETE;
}

  2. Download the Sand Stone Cliff images archive from FreePBR.com called sandstonecliff-ue and install it on your system.

  3. Replace “IMAGE_PBR_PATH” in the code with the actual path to the unzipped Sand Stone Cliff files.

Do not worry about IsShaderDriver() or the specific return values.

 This should result in a scene similar to:

  • No labels
