Growing Organizations

The curse of all larger organizations is that they can not afford to do anymore what they want, but they have to align to the needs and demands of their customers. However, if the organization incorporates also system analysis and consulting, a firm basis for cooperation between the customer and the organization can be established.My goals were always experimental and pioneric, I tried not to make profit, but to keep the costs as low as possible, while also keeping the costs for my customers also as low as possible. However, being too good and overcompetitive can be unwanted in some countries. Rather than doing the best what you can do, you should perform as crappy as the others do.But the battle is not over yet, indeed it hasn't even started yet, so we will continue to be the most competetive and priceworthy company of the world while keeping quality at the best it can be. That is our vision, and always will be.If you want some numbers, here are some:■ .com, .net, .org, etc... Domain hosting: 10 per year.■ Domino based Notes or Web application hosting: 10 per started GB per year (including unlimited bandwidth up to 4 TB space).■ Blog Site: 10 per started GB per year.■ Asus High End Laptops: 940 including full quality control, complete installation and configuration of OS and applications (open office, etc..), and lifetime warranty on support services.■ Solving problems which nobody else in the world can do: 100 per hour (You will first get an work time estimate, and you only pay if you are satisfied with the solution, and get a detailed breakdown of all tasks involved).

      I started to implement quads for tessellation, and at that point the shader system reached the point of being unmanageable. Rendering an object to a shadow map and to a color buffer are two different processes that require two different shaders. Turbo introduces an early Z-pass which can use another shader, and if variance shadow maps are not in use this can be a different shader from the shadow shader. Rendering with tessellation requires another set of shaders, with one different set for each primitive type (isolines, triangles, and quads). And then each one of these needs a masked and opaque option, if alpha discard is enabled.
      All in all, there are currently 48 different shaders a material could use based on what is currently being drawn. This is unmanageable.
      To handle this I am introducing the concept of a "shader family". This is a JSON file that lists all possible permutations of a shader. Instead of setting lots of different shaders in a material, you just set the shader family one:
      shaderFamily: "PBR.json" Or in code:
      material->SetShaderFamily(LoadShaderFamily("PBR.json")); The shader family file is a big JSON structure that contains all the different shader modules for each different rendering configuration: Here are the partial contents of my PBR.json file:
      { "turboShaderFamily" : { "OPAQUE": { "default": { "base": { "vertex": "Shaders/PBR.vert.spv", "fragment": "Shaders/PBR.frag.spv" }, "depthPass": { "vertex": "Shaders/Depthpass.vert.spv" }, "shadow": { "vertex": "Shaders/Shadow.vert.spv" } }, "isolines": { "base": { "vertex": "Shaders/PBR_Tess.vert.spv", "tessellationControl": "Shaders/Isolines.tesc.spv", "tessellationEvaluation": "Shaders/Isolines.tese.spv", "fragment": "Shaders/PBR_Tess.frag.spv" }, "shadow": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "Shaders/DepthPass_Isolines.tesc.spv", "tessellationEvaluation": "Shaders/DepthPass_Isolines.tese.spv" }, "depthPass": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "DepthPass_Isolines.tesc.spv", "tessellationEvaluation": "DepthPass_Isolines.tese.spv" } }, "triangles": { "base": { "vertex": "Shaders/PBR_Tess.vert.spv", "tessellationControl": "Shaders/Triangles.tesc.spv", "tessellationEvaluation": "Shaders/Triangles.tese.spv", "fragment": "Shaders/PBR_Tess.frag.spv" }, "shadow": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "Shaders/DepthPass_Triangles.tesc.spv", "tessellationEvaluation": "Shaders/DepthPass_Triangles.tese.spv" }, "depthPass": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "DepthPass_Triangles.tesc.spv", "tessellationEvaluation": "DepthPass_Triangles.tese.spv" } }, "quads": { "base": { "vertex": "Shaders/PBR_Tess.vert.spv", "tessellationControl": "Shaders/Quads.tesc.spv", "tessellationEvaluation": "Shaders/Quads.tese.spv", "fragment": "Shaders/PBR_Tess.frag.spv" }, "shadow": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "Shaders/DepthPass_Quads.tesc.spv", "tessellationEvaluation": "Shaders/DepthPass_Quads.tese.spv" }, "depthPass": { "vertex": "Shaders/DepthPass_Tess.vert.spv", "tessellationControl": "DepthPass_Quads.tesc.spv", "tessellationEvaluation": "DepthPass_Quads.tese.spv" } } } } } A shader family file can indicate a root to inherit values from. The Blinn-Phong shader family pulls settings from the PBR file and just switches some of the fragment shader values.
      { "turboShaderFamily" : { "root": "PBR.json", "OPAQUE": { "default": { "base": { "fragment": "Shaders/Blinn-Phong.frag.spv" } }, "isolines": { "base": { "fragment": "Shaders/Blinn-Phong_Tess.frag.spv" } }, "triangles": { "base": { "fragment": "Shaders/Blinn-Phong_Tess.frag.spv" } }, "quads": { "base": { "fragment": "Shaders/Blinn-Phong_Tess.frag.spv" } } } } } If you want to implement a custom shader, this is more work because you have to define all your changes for each possible shader variation. But once that is done, you have a new shader that will work with all of these different settings, which in the end is easier. I considered making a more complex inheritance / cascading schema but I think eliminating ambiguity is the most important goal in this and that should override any concern about the verbosity of these files. After all, I only plan on providing a couple of these files and you aren't going to need any more unless you are doing a lot of custom shaders. And if you are, this is the best solution for you anyways.
      Consequently, the baseShader, depthShader, etc. values in the material file definition are going away. Leadwerks .mat files will always use the Blinn-Phong shader family, and there is no way to change this without creating a material file in the new JSON material format.
      The shader class is no longer derived from the Asset class because it doesn't correspond to a single file. Instead, it is just a dumb container. A ShaderModule class derived from the Asset class has been added, and this does correspond with a single .spv file. But you, the user, won't really need to deal with any of this.
      The result of this is that one material will work with tessellation enabled or disabled, quad, triangle, or line meshes, and animated meshes. I also added an optional parameter in the CreatePlane(), CreateBox(), and CreateQuadSphere() commands that will create these primitives out of quads instead of triangles. The main reason for supporting quad meshes is that the tessellation is cleaner when quads are used. (Note that Vulkan still displays quads in wireframe mode as if they are triangles. I think the renderer probably converts them to normal triangles after the tessellation stage.)


      I also was able to implement PN Quads, which is a quad version of the Bezier curve that PN Triangles add to tessellation.



      Basically all the complexity is being packed into the shader family file so that these decisions only have to be made once instead of thousands of times for each different material.

      I'm back from I/ITSEC. This conference is basically like the military's version of GDC. VR applications built with Leadwerks took up about half of Northrop Grumman's booth. There were many interesting discussions about new technology and I received a very warm reception. I feel very positive about our new technology going forward.

      I am currently reworking the text field widget script to work with our persistent 2D objects. This is long and boring but needs to be done. Not much else to say right now.

      Here are some screenshots showing more complex interface items scaled at different resolutions. First, here is the interface at 100% scaling:

      And here is the same interface at the same screen resolution, with the DPI scaling turned up to 150%:

      The code to control this is sort of complex, and I don't care. GUI resolution independence is a complicated thing, so the goal should be to create a system that does what it is supposed to do reliably, not to make complicated things simpler at the expense of functionality.
      function widget:Draw(x,y,width,height) local scale = self.gui:GetScale() self.primitives[1].size = iVec2(self.size.x, self.size.y - self.tabsize.y * scale) self.primitives[2].size = iVec2(self.size.x, self.size.y - self.tabsize.y * scale) --Tabs local n local tabpos = 0 for n = 1, #self.items do local tw = self:TabWidth(n) * scale if n * 3 > #self.primitives - 2 then self:AddRect(iVec2(tabpos,0), iVec2(tw, self.tabsize.y * scale), self.bordercolor, false, self.itemcornerradius * scale) self:AddRect(iVec2(tabpos+1,1), iVec2(tw, self.tabsize.y * scale) - iVec2(2 * scale,-1 * scale), self.backgroundcolor, false, self.itemcornerradius * scale) self:AddTextRect(self.items[n].text, iVec2(tabpos,0), iVec2(tw, self.tabsize.y*scale), self.textcolor, TEXT_CENTER + TEXT_MIDDLE) end if self:SelectedItem() == n then self.primitives[2 + (n - 1) * 3 + 1].position = iVec2(tabpos, 0) self.primitives[2 + (n - 1) * 3 + 1].size = iVec2(tw, self.tabsize.y * scale) + iVec2(0,2) self.primitives[2 + (n - 1) * 3 + 2].position = iVec2(tabpos + 1, 1) self.primitives[2 + (n - 1) * 3 + 2].color = self.selectedtabcolor self.primitives[2 + (n - 1) * 3 + 2].size = iVec2(tw, self.tabsize.y * scale) - iVec2(2,-1) self.primitives[2 + (n - 1) * 3 + 3].color = self.hoveredtextcolor self.primitives[2 + (n - 1) * 3 + 1].position = iVec2(tabpos,0) self.primitives[2 + (n - 1) * 3 + 2].position = iVec2(tabpos + 1, 1) self.primitives[2 + (n - 1) * 3 + 3].position = iVec2(tabpos,0) else self.primitives[2 + (n - 1) * 3 + 1].size = iVec2(tw, self.tabsize.y * scale) self.primitives[2 + (n - 1) * 3 + 2].color = self.tabcolor self.primitives[2 + (n - 1) * 3 + 2].size = iVec2(tw, self.tabsize.y * scale) - iVec2(2,2) if n == self.hovereditem then self.primitives[2 + (n - 1) * 3 + 3].color = self.hoveredtextcolor else self.primitives[2 + (n - 1) * 3 + 3].color = self.textcolor end self.primitives[2 + (n - 1) * 3 + 1].position = iVec2(tabpos,2) self.primitives[2 + (n - 1) * 3 + 2].position = iVec2(tabpos + 1, 3) self.primitives[2 + (n - 1) * 3 + 3].position = iVec2(tabpos,2) end self.primitives[2 + (n - 1) * 3 + 3].text = self.items[n].text tabpos = tabpos + tw - 2 end end
