I am teaching myself D3 without too much knowledge on syntax / grammar of javascript. Could anyone explain the use of d as a parameter in the following function literal Resources are placed in the memory pool most appropriate for the set of usages requested for the given resource. This is usually video memory, including both local video memory and AGP memory. The D3DPOOL_DEFAULT pool is separate from D3DPOOL_MANAGED and D3DPOOL_SYSTEMMEM, and it specifies that the resource is placed in the preferred memory for device access. Note that D3DPOOL_DEFAULT never indicates that either D3DPOOL_MANAGED or D3DPOOL_SYSTEMMEM should be chosen as the memory pool type for this resource. Textures placed in the D3DPOOL_DEFAULT pool cannot be locked unless they are dynamic textures or they are private, FOURCC, driver formats. To access unlockable textures, you must use functions such as IDirect3DDevice9::UpdateSurface, IDirect3DDevice9::UpdateTexture, IDirect3DDevice9::GetFrontBufferData, and IDirect3DDevice9::GetRenderTargetData. D3DPOOL_MANAGED is probably a better choice than D3DPOOL_DEFAULT for most applications. Note that some textures created in driver-proprietary pixel formats, unknown to the Direct3D runtime, can be locked. Also note that - unlike textures - swap chain back buffers, render targets, vertex buffers, and index buffers can be locked. When a device is lost, resources created using D3DPOOL_DEFAULT must be released before calling IDirect3DDevice9::Reset. For more information, see Lost Devices (Direct3D 9).

D3 is a JavaScript library for visualizing data with HTML, SVG, and CSS

Treemaps can use different tiling strategies and D3 has several built in (treemapBinary, treemapDice, treemapSlice, treemapSliceDice, treemapSquarify) and the configuration function .tile is used to select one:

Resources are placed in memory that is not typically accessible by the Direct3D device. This memory allocation consumes system RAM but does not reduce pageable RAM. These resources do not need to be recreated when a device is lost. Resources in this pool can be locked and can be used as the source for a IDirect3DDevice9::UpdateSurface or IDirect3DDevice9::UpdateTexture operation to a memory resource created with D3DPOOL_DEFAULT.
partitionLayout.padding(2) View source | Edit in GistRun If we’d like to change the orientation of the partition layout so that the layers run left to right we can swap x0 with y0 and x1 with y1 when defining the rect elements:

Note that treemap, pack and partition are designed to lay out hierarchies where the nodes have an associated numeric value (e.g. revenue, population etc.).
packLayout.size([300, 300]); As with the treemap we must call .sum() on the hierarchy object root before applying the pack layout:
Applications should use D3DPOOL_MANAGED for most static resources because this saves the application from having to deal with lost devices. (Managed resources are restored by the runtime.) This is especially beneficial for unified memory architecture (UMA) systems. Other dynamic resources are not a good match for D3DPOOL_MANAGED. In fact, index buffers and vertex buffers cannot be created using D3DPOOL_MANAGED together with D3DUSAGE_DYNAMIC.

D3 version 4 requires the hierarchical data to be in the form of a d3.hierarchy object which we’ll cover next.This creates a very powerful method of working with data driven documents (like graphs, charts, etc) without having to track the data elements manually or have to create lots of loops. In fact, you can usually tell you are using d3 incorrectly if you have any loops in your code that deals with modifying elements.

Note that I've renamed the parameter from d to foo, but this just changes how you access the parameter within the function. It has no effect outside of the function call. Generally in d3 documentation and tutorials, you'll see d used for the current data element and i used for the index of the current data element. The index is passed in as the second element to the function calls like so: Всего D3T Limited выпустила 1 игру

I see that it points to the data set being worked on, but want to understand the grammar behind this.
rootNode.sum(function(d) { return d.value; }); partitionLayout(rootNode); The partition layout adds x0, x1, y0 and y1 properties to each node.
In the case of d3, it allows you to pass in a function as the second parameter. As you discovered, this function will be called with the current data element as well as the index of the current data element. If the second parameter is not a function, it can use a value instead.

A treemap will represent each country as a rectangle (sized proportionally to the population) and group each region together:

Function of data can be useful to setting up properties dynamically based on your data or business logic. For example, if you would like to color your paragraph depending on the content of the paragraph, you can do so inside your style property function.
Notice that we have called .data(data) function above. The data() function provides data to the selected elements, in our case it is data array. You will learn about data() function in the Data Bindingsection.
Resources are placed in system RAM and do not need to be recreated when a device is lost. These resources are not bound by device size or format restrictions. Because of this, these resources cannot be accessed by the Direct3D device nor set as textures or render targets. However, these resources can always be created, locked, and copied.
function setY(d) { return percent_scale(d.late_percent);} function setX(d) { return time_scale(d.time); } d3.selectAll("circle") .attr("cy", setY) .attr("cx", setX) .attr("r",1); Here I've replaced the anonymous function calls with more standard function definitions and specified the name of the function to be called in the d3 call. This works exactly the same as before. Also note that there is nothing magical about d in this case.

MPQ General Discussion — D3 Go! Forum

For dynamic textures, it is sometimes desirable to use a pair of video memory and system memory textures, allocating the video memory using D3DPOOL_DEFAULT and the system memory using D3DPOOL_SYSTEMMEM. You can lock and modify the bits of the system memory texture using a locking method. Then you can update the video memory texture using IDirect3DDevice9::UpdateTexture.The pack layout is similar to the tree layout but circles instead of rectangles are used to represent nodes. In the example below each country is represented by a circle (sized according to population) and the countries are grouped by region.

var chords = chordGenerator(data); which returns an array of chords. Each element of the array is an object with source and target properties. Each source and target has startAngle and endAngle properties which will define the shape of each chord. Узнать причину. Закрыть. amd 라데온 nvidia 지포스 3D 색감. playsin플레이신. Загрузка..

All pool types are valid with all resources including: vertex buffers, index buffers, textures, and surfaces.
For example the tree layout takes a hierarchical data structure and adds x and y values to each node such that the nodes form a tree-like shape:

Pools cannot be mixed for different objects contained within one resource (mip levels in a mipmap) and, when a pool is chosen, it cannot be changed.

function setY(d, i) { return percent_scale(d.late_percent);} function setX(d, i) { return time_scale(d.time); } d3.selectAll("circle") .attr("cy", setY) .attr("cx", setX) .attr("r",1); Now specifically in the d3 case: A d3.hierarchy object is a data structure that represents a hierarchy. It has a number of functions defined on it for retrieving things like ancestor, descendant and leaf nodes and for computing the path.. .attr('x', function(d) { return d.y0; }) .attr('y', function(d) { return d.x0; }) .attr('width', function(d) { return d.y1 - d.y0; }) .attr('height', function(d) { return d.x1 - d.x0; }); View source | Edit in GistRun We can also map the x dimension into a rotation angle and y into a radius to create a sunburst partition:

The following tables indicate restrictions on pool types for render targets, depth stencils, and dynamic and mipmap usages. An x indicates a compatible combination; lack of an x indicates incompatibility.// Select all of the 'circle' elements (that is <circle>) elements // in the HTML document and put the associated data into an array d3.selectAll("circle") // For each circle element, set the Y position to be the result // of calling percent_scale on the data element late_percent .attr("cy",function (d) { return percent_scale(d.late_percent);}) // For each circle element, set the X position to be the result // of calling time_scale on the data element time .attr("cx",function (d) { return time_scale(d.time);}) // For each circle element, set the radius to be 1 .attr("r",1); This is a very common construct in d3. The first step is always to make a selection to define which set of elements you want to modify (this is the .selectAll in this case). After that, you can chain together additional calls (in this case the .attr calls) that actually perform the desired modifications to the elements. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. packLayout.padding(10) View source | Edit in GistRun partition layout The partition layout subdivides a rectangular space into a layer for each layer of the hierarchy. Each layer is subdivided for each node in the layer:

We use the ribbon shape generator which converts the chord properties into path data (see the Shapes chapter for more information on shape generators).var chordGenerator = d3.chord(); and we configure it using .padAngle() (to set the angle between adjacent groups in radians), .sortGroups() (to specify the order of the groups), .sortSubgroups() (to sort within each group) and .sortChords() to determine the z order of the chords.treemapLayout .size([400, 200]) .paddingOuter(10); Before applying this layout to our hierarchy we must run .sum() on the hierarchy. This traverses the tree and sets .value on each node to the sum of its children:treemapLayout.tile(d3.treemapDice) treemapBinary strives for a balance between horizontal and vertical partitions, treemapDice partitions horizontally, treemapSlice partitions vertically, treemapSliceDice alternates between horizontal and vertical partioning and treemapSquarify allows the aspect ratio of the rectangles to be influenced.When creating resources with D3DPOOL_DEFAULT, if video card memory is already committed, managed resources will be evicted to free enough memory to satisfy the request.

D3 has a number of hierarchy layouts for dealing with hierarchical (or tree) data as well as a chord layout (for network flows) and a general purpose force layout (physics-based simulation). We’ll cover the force layout in a separate chapter..text(function(d) { return d; }); Within this function, we can apply any logic to manipulate the data.
